Biles, of course, has a well-documented crush on the former "High School Musical" star. And, given that the gymnast has been cemented as one of the greatest athletes in history, it's no surprise that Efron would be happy to return the love.
The gymnast won the gold medal in the women's individual all-around final on Thursday afternoon, and the incredible news spread quickly across the internet.
But, those not glued to the event's livestream were stuck waiting to watch the competition when the footage aired on NBC later in the evening. Efron, it seems, was one of those people.
After nabbing the gold medal, Simone sent a tweet to her many fans, thanking them for their support. And, as he had been doing, Efron sent a tweet in response to congratulate Biles on her stunning feat.
But the kicker? He referred to her as a "#hero."
@Simone_Biles Congrats Simone! Can't wait to watch tonight.????????#proud #hero #Rio2016

Biles, in turn, thanked Efron for the kind words and tossed him a compliment of her own.
