Wifey Of: Wladimir Klitschko (Professional Boxing), Scotty McKnight, New York Jets (NFL)
First, she was the precocious daughter/narrator in Remember the Titans. Then, she was the hot (but way too young) cheerleader on the NBC show Heroes. Since those gigs, though, the Nashville star has found time to become a well-known WAG both in the U.S. and abroad.
She dated heavyweight champion boxer Wladimir Klitschko from 2009 to mid-2011, but the sheer difference in size between the two (Klitschko: 6' 6", 242 lbs.; Panettiere: 5' 2", 110 lbs.) proved too much to overcome both in and out of the bedroom. She then moved on to former New York Jets wide receiver Scotty McKnight, who is no longer with the team.
