As if sideboob, boob windows and thigh-high slits weren't already in full force this spring, some of our favorite celebrities flashed us just about everything but their private parts at this year's Billboard Music Awards.

From actress Jennifer Morrison in a sheer-to-the-waist gown showing all but her mid-section to Ke$ha and her side booty and Jenny McCarthy in a midriff-baring '90s inspired top and skirt, these celebrities wowed on yesterday's (May 19) red carpet. Let's just say ... music wasn't all that was on display this year in Las Vegas.
