Guess which hot babe sizzled in a printed short dress and dropped some serious cleavage at the premiere of (500) Days of Summer?

Hint:
- She was spotted displaying that sweet cleavage the second day in a row at a movie premiere event.
- Remember that “pie petition”?

Hit the jump for the answer and some more pics of this hot beauty.

It’s Olivia Munn, the babe responsible for maintaining the TRP for G4TV’s Attack of the Show. Yesterday, she was seen at the LA premiere of Transformers 2. Click here for Olivia’s pie dive.
