Jonah Hill vs. Matthew Morrison

Charlie Sheen

The peril of outdoor interviews: when a gust of wind blew up her dress up on German TV, J-Lo pushed it back down -- and popped out of her top!
Nancy Grace
The family-friendly 'Dancing with the Stars' briefly veered into R-rated territory this year, when the news pundit took a cleavage-exposing dip.
Lady Gaga
She exposed her boobs at the CFDA Fashion Awards -- almost as big a faux pas as accidentally swearing at Anna Wintour!
Nicki Minaj
Fell out of her very low-cut tube top during a live 'GMA' performance. That's one way to say "good morning!"
Khloe Kardashian
Didn't notice when her nipple peeked through her shirt for an entire 'Fox & Friends' interview. Not that she cared.

Her incredible voice and heartbreaking songs made '21' the year's best-selling album -- and we love that her weight doesn't rule her life.
Ryan Gosling
Gorgeous, soulful, talented -- and practically caused a riot when he was overlooked when 'People' magazine named this year's Sexiest Man Alive!
Beyonce
Hands-down, one of the hardest-working women in show biz. If anything, pregnancy has made Sasha Fierce even fiercer!
Emma Stone
