Simone Biles is living out a romance novel fantasy! Just three days after the Olympic gymnast celebrated her 28th birthday, she posted a photo of herself holding hands with her husband Jonathan Owens as they rode horses in the ocean. She shared more the photos in her Instagram Stories, documenting Owens' horse making its way through chest-high waters. In another photo, Biles smiles at the camera as she rides along. The special experience follows Biles’ cowboy-themed birthday where she wore a black cowboy hat and complimenting cowboy boots and posed with a black, heart-shaped birthday cake. She finished off her outfit with a cowhide-style strapless top and a white skirt. Biles' husband paid tribute to her on social media with a message on her big day. "Happy birthday to my wife, my queen, my best friend, my everything," Owens, 29, wrote on Instagram alongside photos of the couple together. "Being married to you is everything i could’ve ever asked for, a beautiful, funny, intelligent and confident person that motivates me to be the best version of myself everyday. I’m so blessed to have met someone as amazing as you baby, i cherish every moment that we spend together." Her birthday and their latest outing come less than a month after the couple returned from their South African honeymoon. Although they got married in April 2023, it wasn’t until two years later that the athletes embarked on their long-awaited romantic holiday.

The trip was a long time coming. After their wedding, the couple has been busy with their respective careers. Owens left the Green Bay Packers and signed a two-year free-agent contract with the Chicago Bears. Simone, meanwhile, competed in the Paris Summer Olympics, taking home four medals. Last summer, Owens explained that supporting one another is an element of their relationship he loves. "I love watching [it] from an athlete's perspective because that's how you'd be great in any sport, is just being consistent and doing the same thing consistently good every day," he said. "You know what I mean? I love to watch it and I love to be out there and be a cheerleader."
