Singer Cassie is known for her high-profile romance with ex-boyfriend Sean Combs, a.k.a. P. Diddy, however, the R&B singer found her happily ever after much later with her husband, Alex Fine.

The “Official Girl” singer met Alex through her ex and fans are curious about who the personal trainer is.

Alex is a professional bull rider, model and fitness enthusiast. He is also the founder of Almost Home, an online platform dedicated to helping others through fitness and wellness.

“What you can expect from us is a community based platform connecting you with the best trainers, coaches, yoga instructors, nutritionists, life coaches, therapists, and entrepreneurs,” the official website states. “Fitness and wellness programs for a healthy body, expert advice and shared stories to inspire your mind, and some top tier gear to keep you looking good and stay motivated while you’re working towards your individual goals.”

How Did Cassie and Alex Fine Meet?

Cassie’s ex-boyfriend, Diddy, initially hired Alex to be her personal trainer. After Diddy and Cassie’s 2018 split, Alex and Cassie went Instagram official with their relationship in January 2019.

A source told People that Diddy believed “there was absolutely overlap” between the two relationships. “Cassie wanted a personal trainer, so Diddy hired Alex for her,” an insider claimed that month. “Then Cassie and Alex started hooking up before her relationship with Diddy was over.”

When Did Cassie and Alex Get Married?

Cassie and Alex got engaged in August 2019, two months after they revealed they were expecting their first child. The pair tied the knot two weeks later in an intimate Malibu ceremony.

Do Cassie and Alex Fine Have Kids?

Alex and Cassie welcomed their first child, a baby girl named Frankie Fine, on December 6, 2019. The pair welcomed baby No. 2, daughter Sunny Cinco, in March 2021.

Cassie announced she was pregnant and expecting her third child with Alex in February 2025. The following month, the singer revealed the gender of their unborn baby, their first boy!

“Her life with him and their two girls is so wholesome, he’s not just the best partner, he’s the best dad, Cassie feels very blessed to have him by her side for this journey,” an insider exclusively told In Touch in April 2025. “She adores her girls, but she’s thrilled to be having a son, it’s just a different ball game and something she’s always wanted to experience.”

How Has Diddy Reacted to Cassie’s New Romance?

Diddy seemingly referenced his ex in the June 2022 release of his single “Gotta Move On.”

“You found a new man, so I gotta move on/Guess you got a new agenda, with someone you barely know,” the “Last Night” rapper declared on the track. “I won’t say you’re wrong/Guess you had to move on.”

Hours later, Alex seemingly threw shade toward Diddy via his Instagram Stories after sharing a link to an “LGBT” foundation.

“Happy Pride to all my LGBTQ+ friends,” Alex wrote with a link to an “LGBT foundation” while hinting at the Bad Boy Mogul’s recent release. “Attached is a charity that helps people who are in the closet and GOTTA MOVE ON. Along with other resources.”

How Alex Fine Supported Cassie Amid Diddy Trial

Cassie took the stand against Diddy during his trial in May 2025 as he faces racketeering conspiracy, sex trafficking and other charges.

Alex supported his wife throughout her testimony, except for a portion of the hearing on May 14, 2025, when he was ordered by the judge to leave the courtroom. Following the fourth day of Cassie taking the stand, Alex shared his support outside the courthouse.

“The world has gotten to witness the strength and bravery of my wife, freeing herself of her past. There has been speculation online surrounding how it must feel for me to sit there and listen to my wife’s testimony,” Alex said via Cassie’s lawyer, Douglas Wigdor, on May 16, 2025.

He later added, “So, to [Diddy] and all of those who helped him along the way, please know this: You did not. You did not break her spirit nor her smile that lights up every room. You did not break the soul of a mother who gives the best hugs and plays the silliest games with our little girls. You did not break the woman who has made me a better man.”
