Matt Rife Girlfriend: Inside His Relationship With Fitness Coach Mariah Morse

Mariah Morse became a familiar name to Matt Rife fans in 2025 after the comedian began dating the fitness coach, bodybuilder and social media creator. Their relationship quickly became public, with the pair appearing together at comedy shows, sharing vacation photos and supporting each other’s careers.

There has since been an important update. Rife and Morse reportedly ended their relationship in early 2026 after dating for less than a year. As of September 2026, there is no publicly confirmed indication that they have reunited. Rife was later photographed holding hands with another woman, although a source close to him said she was a friend rather than a new girlfriend.

Even though the relationship has ended, interest in Morse remains high. She has established her own career in fitness, competed in bodybuilding, built a large social media following and worked as a personal trainer and nutrition coach.

Who Is Mariah Morse?

Mariah Morse is a fitness professional, online content creator and competitive bodybuilder. She became more widely known during her relationship with Matt Rife, but she had already been building a career based around training, nutrition and wellness.

Morse is a certified personal trainer and nutrition coach who uses social media to share workouts, meal ideas and parts of her everyday fitness routine. By late 2025, she had attracted more than 200,000 followers on Instagram and had partnerships connected to fitness brands including 1st Phorm, Alphalete and DFYNE.

Her online presence is focused heavily on the work required to maintain her physique. Rather than posting only polished fitness photos, Morse has regularly shown training sessions, exercise routines and meals that fit into her approach to health.

Bodybuilding eventually became another major part of that work.

Mariah Morse Is a Competitive Bodybuilder

Morse took her fitness career onto the competition stage in September 2025 when she participated in the Summer Shredding Championship.

She won the Bikini Overall title, marking an important achievement in her bodybuilding career. Rife attended the event and publicly celebrated the result, showing that their relationship involved support in both directions rather than Morse simply accompanying him to comedy events.

After the competition, Morse shared photographs from the event and reflected on the people who had supported her through the difficult parts of preparing for the stage.

Competitive bodybuilding requires months of structured training, careful nutrition and extensive preparation. Morse had already been documenting much of that lifestyle online, but winning the Bikini Overall title provided a more visible example of how seriously she approached the sport.

It also gave followers a clearer sense of her identity outside her relationship with Rife.

When Did Matt Rife and Mariah Morse Start Dating?

Public interest in the relationship began in March 2025.

Rife and Morse were spotted holding hands while entering a club in Rhode Island. Around the same period, they were seen together in a group photograph with friends, creating speculation that the two were dating.

Their relationship was reported publicly on March 31, 2025. At the time, it was not clear exactly when they had started seeing one another, although they appeared comfortable enough together that Morse had already spent time with Rife’s dog, Hammer.

The pair initially avoided making their romance a major part of either of their social media accounts.

That gradually changed.

Morse included Rife in an Instagram post in May 2025. The collection featured several personal moments, including the couple holding hands and spending time together while Rife got a tattoo.

Rife later began including Morse in his own social media posts as well.

Their Relationship Became More Public

As 2025 continued, Rife and Morse stopped hiding the fact that they were together.

Morse appeared at several stops connected to Rife’s Stay Golden Tour, including performances in Las Vegas and Florida. Rife also shared a backstage photograph of the pair holding hands at Madison Square Garden.

Their public moments suggested that Morse had become part of his life on the road rather than someone he saw only between shows.

The comedian returned that support when Morse competed in bodybuilding, including being there for her Summer Shredding Championship victory.

For Rife’s 30th birthday in September 2025, Morse shared a particularly personal message describing qualities that people who only knew him through comedy might not see. She wrote about his humor away from the stage, his ability to remember small details and the effort he made to brighten other people’s days.

It was one of the clearest indications at the time that the relationship had become serious.

Mariah Morse Is Also a Dog Lover

Fitness is a major part of Morse’s public identity, but another recurring feature of her social media presence is her Alaskan Malamute, Kona.

Morse adopted Kona in 2021 and has shared many parts of their life together, from hikes and road trips to holidays and everyday moments.

She once posted about the experience of getting a dog in your 20s and reflected on the unconditional companionship pets can provide.

Her love for dogs also became part of her connection with Rife.

Rife has a pit bull named Hammer, and Morse spent time with him while she and the comedian were together. In fact, her appearance with Hammer was one of the early details that attracted attention when reports of the relationship first surfaced in March 2025.

Matt Rife and Mariah Morse Appeared Together Frequently

The relationship became increasingly visible through the second half of 2025.

They traveled together, attended events and occasionally shared affectionate photographs online. During Halloween, Morse dressed as the Annabelle doll while Rife included her in pictures from their celebration.

The couple also combined their public profiles professionally in an unusual way.

Rife and Morse appeared as romantic interests in the music video for the Red Clay Strays song “If I Didn’t Know You.” The timing became particularly noticeable because the video emerged around the period when news of their real-life breakup was becoming public.

What had appeared to be another public moment from their relationship instead became one of the final projects connecting them as a couple.

Why Did Matt Rife and Mariah Morse Break Up?

Reports emerged on February 9, 2026, that Rife and Morse had ended their relationship.

The exact reason for the split has not been publicly explained.

At the time the breakup was reported, the two had also stopped following each other on social media. Neither Rife nor Morse publicly provided a detailed explanation about what caused their relationship to end.

That means claims about arguments, cheating or another person causing the breakup would be speculation unless either Rife or Morse chooses to discuss the situation themselves.

Based on the publicly available timeline, they were romantically linked for roughly a year or less.

Their split also followed what had appeared to be a particularly close period. Only months earlier, Morse had celebrated Rife’s birthday with an affectionate tribute, while Rife had publicly supported her bodybuilding success.

Relationships, of course, can change quickly away from social media.

Does Matt Rife Have a New Girlfriend?

There is currently no clearly confirmed new girlfriend following Rife’s breakup with Morse.

In August 2026, Rife was photographed holding hands with a woman while attending a Red Clay Strays concert in Boston. The sighting immediately caused speculation that he had started another relationship.

However, a source close to Rife said the woman was simply a friend and explained that he was helping her move through the crowd. No relationship announcement followed.

Rife has also recently worked with country singer Ashley Cooke, appearing as her romantic interest in the music video for “Baby Blues.” Cooke said in September 2026 that she and Rife had become close, but she described the romance in the video as fictional and said it ended when filming stopped.

As a result, there is not enough verified information to identify someone else as Rife’s current girlfriend.

Where Is Mariah Morse Now?

Morse continues to have an identity and career that does not depend on Rife.

Her work as a personal trainer, nutrition coach, fitness creator and bodybuilder had already become well established while they were dating. Her Bikini Overall victory in 2025 was another step in building that career independently.

The relationship may have introduced Morse to a much larger audience, particularly among Rife’s comedy fans, but fitness remains the foundation of her public profile.

She regularly built her content around exercise, nutrition and her own training progress, giving followers practical insight into the lifestyle behind competitive fitness.

That makes the description of Morse simply as “Matt Rife’s girlfriend” increasingly outdated for two reasons. The pair are no longer together, and Morse had developed a substantial professional presence of her own.

Matt Rife and Mariah Morse’s Relationship Today

Matt Rife and Mariah Morse were one of the comedian’s most visible recent relationships.

What began quietly in early 2025 became increasingly public through photographs, comedy shows, vacations, bodybuilding events and affectionate social media posts. Morse supported Rife while he toured, while Rife was present during one of the biggest moments of her competitive fitness career.

By February 2026, however, the relationship had ended. Neither has publicly provided a detailed explanation for the split, and there is currently no reliable evidence that they have reconciled.

For anyone searching for Matt Rife’s girlfriend today, the important update is that Mariah Morse should now be described as his former girlfriend. As of September 2026, Rife has not publicly confirmed another relationship.

Morse, meanwhile, continues to be known for far more than the comedian she once dated. With her bodybuilding accomplishments, coaching work and growing fitness platform, she has built a career and audience of her own.
