Let's face it. If there's one body part that's gotten a lot of attention over the past couple of years, it's the butt.

Stars have, of course, been playing this asset up: Miley Cyrus put hers on full view with her endless twerking, while Christina Aguilera and actresses such as Mad Men's Christina Hendricks have shown off their derrieres in form-fitting frocks that put them on the best dressed lists. Victoria's Secret models like Cara Delevingne or Karlie Kloss get paid to show off their bums on the runway, while Tyra Banks taught us all about the booty tooch.

Then there are pop stars like Jessica Simpson, who renewed America's interest in tight "daisy dukes" in the 2005 remake of The Dukes of Hazard. More recently, Jennifer Lopez and Iggy Azalea paid homage to the backside with their hot single, "Booty."

In honor of the public's ongoing fascination with butts, we're showing love for some of the most famous. Whether they're big and bubbly or toned but just as perky, we reveal 19 celebrities who have shown off their buns and were proud doing it. Here are the Best Butts of Hollywood.
