Sandra Bullock has raved about locking lips with Scarlett Johansson at the MTV Movie Awards over the weekend. “Ryan is right – Scarlett is a great kisser,” the Oscar-winner declared. Johansson had stepped in for her husband Ryan Reynolds, who co-stared with Bullock in The Proposal, at the awards show where the on-screen duo were nominated for Best Kiss. “I thought you should have won … it was a great kiss,” the 25-year-old told The Blind Side star on stage, at which point they moved towards one another and began kissing.
