Can You Guess The Famous Cleavage?

This famous singer, actress and mega-star is used to showing off her "talents."

Her chest, and her family, are no strangers to the spotlight -- Dad was a top-selling musical act in his prime and she followed in his "bootsteps" with one of the highest grossing musical tours of the last decade. Several of her siblings also entered the entertainment business -- her brother is in a popular band, her other sibling an actress and the third is a guitarist.

She was ranked number thirteen on Forbes' 2010 Celebrity 100 and also holds a Guinness World Record. She did it all "just by being herself."
