Rio Olympics 2016: Simone Biles, actor Zac Efron exchange kisses

The 19-year-old gymnast made her country proud, winning a record four gold medals while adding a bronze at the Olympic Games in Rio, and became an international household name in the process.

Everyone wants a little time with the pint-sized wonder, who cemented her position as the greatest gymnast ever. That includes celebrity heartthrob Zac Efron. 

Biles met the actor who is popular for his roles in films such as "High School Musical" and "That Awkward Moment." The two met up up backstage Tuesday, following Biles' historic run. They hit it off immediately, exchanging selfies and even a couple smooches. 

Biles returned the favor, planting a couple on the movie star.
