Biles shared with her fans on Instagram a photo of her cuddling up to Ervin, writing: "Always smiling with you."
Meanwhile, Biles' beau also took to social media to sing her praises for being recognized by the USA Gymnastics Hall of Fame.
"Words cannot express how incredibly proud I am of you, all you've accomplished & how well you carry yourself," Ervin captioned a photo of the two all dressed up and posing at the event. "You make me feel like I am the luckiest man alive. Congratulations on your induction to the USA Gymnastics Hall of Fame! I can't wait to see what the future has in store."
When ET caught up with Biles back in April, the Dancing With the Stars alum admitted that she's not too experienced when it comes to the world of dating. "I have never had a boyfriend in my life," she dished. "At 20 years old, I feel like you should have gone through those things and gone on dates. I have been on, like, maybe one proper date."
