Cassie has found her happily ever after.

The “Me & U” singer and her boyfriend Alex Fine got engaged during a Western-themed ceremony on Aug. 24. Cassie shared video footage of the romantic proposal at Compton Cowboys stable.

As the sun set, Fine got on horseback as his future wife walked in holding a bouquet of flowers. He got off the horse and down on one knee before popping the question below an arch with their initials. They celebrated with an embrace and kiss.

“My favorite day ever! #MrsFine 💍 8.24,” Cassie captioned the video, which was soundtrack by The O’Jays “Forever Mine.”

Cassie also shared a photo of her and her fiancé with their arms around each other. “I love you best friend. I can’t wait to spend the rest of my life with you,” she added.

Fine, who is a physical trainer and competitive bull rider, also gushed over his bride-to-be. “This moment will always be so special to me,” he wrote. “I get to marry my best friend in the whole world. How am I so lucky!”

Cassie, who celebrated her 33rd birthday on Monday, and Fine are expecting their first child together. In June, Cassie confirmed that she was pregnant with a baby girl.

She also shared photos from a maternity shoot. The future Mrs. Fine showed off her baby bump in the stunning images, which were shot on the beach.

The engagement comes nearly a year after Cassie ended her decade-long relationship with Diddy.

Congrats to the couple!
