Zac Efron Surprises Final Five, Kisses Simone Biles on Cheek

Zac Efron surprised Simone Biles and the rest of the U.S. Women's Olympic Gymnastics team on Today, showing up to greet them in the studio. The Final Five thought they were in for a routine interview with host Hoda Kotb, and were shocked and delighted to see Efron walk through the door.

Zac talked to Today about meeting the athletes, and said, "They have such heart, and there was clearly something special."

Efron and Biles have been engaging in Twitter flirtation for several days:

When the Neighbors star visited his fans in Rio, he was sure to make sure and give gold medalist Biles a kiss on the cheek.

In a backstage interview, Efron admitted he had butterflies before meeting the gymnasts.
