Rising pop sensation Justin Bieber returned the favor and planted a wet one right on Rihanna‘s cheek last Friday (Jan 29) while he was backstage at rehearsals for the 52nd Annual Grammy Awards. The Biebz certainly has a way with the ladies and it’s no secret that he has a big crush on the Barbados native, but surprisingly this isn’t his first “kissing” encounter with her. He showed up to a photo shoot recently with red lipstick on his face, which was the result of a kiss from Rihanna. But according to 15-year-old Justin, Rihanna said he was “too young” when he asked her out on a date.

“Yea, I asked her out,” Justin said in an interview on Chelsea Lately. “It didn’t go so well since I’m not with her. I asked her out and she was basically like, ‘You’re too young.’”

Maybe in about 3 – 5 years Justin 😉 More pics of Justin Bieber and Rihanna below…
