Cassie and her new boo are going strong.

Following her breakup with Diddy last year, the singer-model has been dating trainer Alex Fine. The couple met while Fine was training Cassie and hit it off.

In honor of International Women’s Day, the 25-year-old took to Instagram Stories to profess his love for Cassie. “Strong, beautiful, sweet, thank you,” Fine captioned a photo of the couple with the hashtag #InternationalWomensDay.

The “Me & U” singer and physical trainer went public with their romance in December. They haven’t been shy about their relationship, posting PDA-filled photos on Instagram.

On Valentine’s Day, Fine penned a heartfelt note to his girlfriend. “Happy Valentines Day,” he wrote. “Thanks for not throwing away my crocs and not getting mad when I eat all your food if you leave it in the fridge longer than 5min.”

Diddy and Cassie announced their breakup last fall after a decade-long relationship. Following their split, Diddy shared his love for Cassie on social media, dedicating Michael Jackson’s “The Lady in My Life” to his ex.

In between modeling for Fashion Nova, Cassie continues to record music. Her vocals can be heard on “Way to the Show” off Solange’s new album When I Get Home.
