Hayden Panettiere and Wladimir Klitschko pose together: What happens when an unstoppable force meets an indestructible cheerleader? Haydenko! Er, Wladattiere!

We're hoping the hot young actress and the 55-3 heavyweight boxer stay together because any guy who comes after him is going to have to deal with a serious inferiority complex. Unless, of course, she starts dating his brother.
These two haven't been seeing each other long and there's not a ton known about the nature of their relationship but it somehow works. There's no shortage of interest, they're both relatively successful and one of them is a knockout.
