What ass belongs to this popstar? She was recently photographed on vacation as she "hey, hey, hey, hey, just walks away".
And it's not: Mariah Carey, Barry Manilow, or Camryn Manheim!
The answer is after the jump!!!
It's none other than Kelly Clarkson! The original American Idol will be going on the road for the second time this summer on her Addicted Tour! Hopefully the weight will come off during all that jumping during "Since U Been Gone"!
