Simone Biles freaks out when crush Zac Efron surprises her

Oh sure, having Zac Efron pay you a surprise visit and then kiss you on the cheek, NBD, right?

As if Olympic sensation Simone Biles didn't already have plenty of reasons to smile -- like maybe her four gold medals and one bronze -- she's got another reason now.

Actor Zac Efron -- fulfilling teenage crush goals everywhere -- popped over to Rio to find Biles and plant a surprise smacker on her.

"He kissed me on the cheek, just letting y'all know," Biles shared in a tweet.

Biles' fans know the gymnast has a soft spot for the actor. And Efron has shown that the appreciation is pretty mutual -- he even tweeted her back in July to wish her good luck in the Olympic trials.

No cardboard cut-outs of Efron for Simone. This time, it was a real-life smooch and the Internet loved it so much it was retweeted more than 110,000 times.

Efron went all fan-boy on Biles, letting us know that his "Olympic dream came true." We appreciate the update.

Just so we're all clear, HE kissed her first, ok?
