Zac Efron surprised Simone Biles with a kiss on the cheek in Rio

Simone Biles has won four gold medals and one bronze at her very first Olympic games. But all that hardware is nothing compared to the kiss she just received from Zac Efron. 

In a video posted to her Snapchat Tuesday afternoon, Efron is seen planting a quick kiss on Biles' cheek. Apparently he traveled to Rio just to see the gymnast and congratulate her in person. The kiss was also a surprise: Minutes after sharing the kiss on Snapchat, Biles reposted the video on her Twitter account, writing, "had to do a retake [because] I thought we were taking a picture, then he kissed me instead."

Biles' crush on the actor is well-known: The two have been flirting on Twitter almost incessantly. The gymnast recently told People that she thought Efron "very good looks" and that she "heard he's nice." She even has a leotard covered with pictures of Efron's face. 

Now, she's gotten up close and personal with the real thing. Here is the glorious moment that Efron's lips met Biles' cheek. 

And here's the full vid:

Biles even got a chance to kiss him back - though she's so short that Efron had to bend his knees and Biles had stand on tiptoe just to reach his cheek. She posted a Boomerang of the return kiss on Twitter with the caption "on cloud 9."

A gold medal and a Zac Efron kiss in one day? Simone Biles truly is an Olympic champion.
