Sandra Bullock gives Scarlett Johansson a passionate kiss onstage while accepting the MTV Generation Award during the 2010 MTV Movie Awards at Universal Studios’s Gibson Amphitheatre on Sunday (June 6) in Universal City, Calif.

Scarlett replied, “I’m here because [my husband Ryan Reynolds] couldn’t be here and I wanted to be here when you accepted your award for Best Kiss.”

Said Sandra, “We didn’t win that.”

Scarlett said, “I thought if you did win, it would be really sweet and soft…” Cue lip lock for girl-on-girl action!
