Accompanied by her bestie, singer-songwriter Jake Miller, the gold medalist got the Olympic rings inked on her arm.
Taking to Instagram to share the occasion with her three million followers, the duo proudly showed off their choice of designs.
“First tat. Never too late to get the rings tattooed,” Biles posted.
“Thanks for taking me neighbour.”
Biles, who has five Olympic medals under her belt, would understandably want to mark that milestone for life.
Miller made a joke about the American gymnast being so nervous about the whole experience:
“Took Simone Biles to get her first tattoo last night. I think she was more nervous than she was at the Olympics,” he wrote on Instagram.
The pair looked super happy after seeing the final result.
