Kisses Scarlett Johansson!
The girl-on-girl action went down last night -- after Sandy got a huge standing ovation while receiving something called the Generation Award.
After the smooch, Bullock addressed the attention now placed on her personal life, saying "Can we please go back to normal because therapy is really expensive. Go back to making fun of me, I don't care, it's time to get back to normal."
The kiss comes around the 4:00 mark.
