As random celebrity couples go, Hayden Panettiere being spotted poolside in Miami with Ukrainian boxing champ Wladimir Klitschko would be pretty high up there.

Okay, it would be on top of the list.

Klitschko is 33, so he's Hayden's type. The 20-year-old previously dated her Heroes co-star Milo Ventimiglia and British TV presenter Steve Jones, both 30-plus.

He holds the IBF, WBO, and IBO world heavyweight titles, but if Wladimir is holding Hayden Panettiere the way we think, that would be even more impressive...

Wladimir Klitschko admires the poolside scenery: Hayden Panettiere.

He's 6'6" and she's 5'1", and they might seem to have little in common, but sometimes opposites attract. That's pretty much all we've got at the moment.
