Simone Biles celebrated another trip around the sun in the best fashion.
Biles, who turned 29 years old on Saturday, March 14, took to Instagram on Monday, March 16, to show off her curves in a bikini. While posing on a yacht, Biles stunned in a black bikini top featuring triangle cups and halter straps. She styled the piece with high-waisted black denim cutoffs and a sheer cover-up, which she wore untied.
The Olympian glammed up her look with silver rings, a hand chain and a black Van Cleef & Arpels bracelet. She further accessorized with a silver chain necklace and dainty hoop earrings.
Biles went makeup-free in the pic and wore her hair parted down the middle and styled in long curls.
In one of the photos, Biles was surrounded by gold and white balloons spelling out her name.
Elsewhere in the social media dump, Biles showed off a trendy butter yellow outfit. She stunned in a halter corset top and with floral details that cascaded into a cowl waist skirt. She teamed the look with a colorful Louis Vuitton purse and diamond jewelry.
“This is 29 ????,” she captioned the post.
Biles’ husband, Jonathan Owens, supported her in the comments section. “And more beautiful than ever ????????????,” he gushed.
In November 2025, Biles opened up about her figure and her decision to get a breast augmentation via TikTok.
“I got my boobs done June 16, but I know everybody wants to know: Who was the doctor? Where did I get them done? Did I do over or under? And what size implants did I do?” she said, noting that she saw Dr. Kriti Mohan in Texas.
Biles revealed that she spoke with her plastic surgeon at the time about her desired results and “we decided under the muscles was gonna be the best option for me based on my inspiration photos to get the most natural look.” She shared that she got 310cc “extra filled silicone” implants with a “high profile.”
She also added that the implants were the best for her frame because she’s 4-foot-8 and 105 pounds, and has “broad shoulders.”
