What is the name of the song that plays when Audrina catches Justin Bobby kissing a red head at the bar?

Question

It is the part right before the commercial break when Lauren says, "He just kissed her!" or something like that and then Audrina looks over. It sounds kind of like a rap-rock edgy mix. It's hot.

Answer 1

I think its Britney Spears "Piece of Me"

If some of the words are:

"I'm Mrs. Lifestyles of the Rich and Famous, you want a Piece of Me, I Mrs. Oh my God that Britney's shameless, you want a piece of me".........
