After a long campaign before Hollywood’s biggest night, the 50 year-old actress was clearly not prepared to give an acceptance speech, saying, “Yeah, I am kind of speechless. When I watched Kate [Winslet] two years ago, it looked so f***ing easy.”

Melissa’s “speech” just went down from there – it must have been one of the worse (if not the worst!) Oscar acceptance speech ever. I just felt sorry for her. What a mess. Not to mention, Melissa is also on top of our worst dressed celebs list.

Melissa apologized for dropping the bomb as soon as she left the stage. How embarrassing. We would expect Christian Bale, who won the Oscar for Best Supporting Actor, to do something like that… yet he didn’t!

Melissa said, “I apologize to anyone that was offended. It was probably a very inappropriate place to use that word in particular.”

As for her controversial “For Your Consideration” ads? “It was no campaign,” she said. “I wanted a pretty photograph in a magazine. That’s all it was.”
