Jennifer Lopez

Her waist is small, her curves are kickin’… J.Lo’s butt is arguably the butt that started it all. At first, she didn’t get what all the hype was about and insisted it was “only” a butt. However, she has since embraced her backside, releasing the song “Booty” with fellow ass master Iggy Azalea and having a good laugh with James Corden about rumors that she had her biggest, um, asset insured for $1 million. “No! There is no such thing as that,” she insisted, wondering how having it insured could be at all useful. “Something happens to it? It disappears? Somebody steals it?” she asked.

Take our quiz to see how well you know your celebs from behind.
