Can You Guess the Celebrity Cleavage?

Today's cleavage belongs to an entertainer who's known for being a little bit wild girl and a crunkcore queen.

Her first album came out in 2010 and she's been filling up the airwaves with synthpop goodness ever since. Hey lyrics always speak of a party animal lifestyle, so she's also known for going pretty hard. One of her first videos is for a song that has an onomatopoeic title. If we say any more, then you'd probably figure out who it is.

Can you guess who owns this fantastic celebrity cleavage?
