A Tipsy Diane Keaton Totally FREAKS OUT When Justin Bieber Surprises Her On Ellen! Watch Her Go For A Kiss HERE!
Diane Keaton is one of the biggest Beliebers out there!
Sipping on some of her own favorite "The Keaton" wine (with ice cubes!) the actress was clearly excited to be on the show during "Bieber week" — but didn't realize how much the pop star had grown up over the past few years!
After Ellen showed a few of Bieberoni's recent drool-worthy Calvin Klein ads, Keaton REALLY started to swoon!
Then all hell broke loose when Biebs came out from backstage himself and the 69-year-old tried to plant one on him! LOLz!
Check out the funny clip (below)!
