hayden-wladimir

Hayden Panettiere broke up with Wladimir Klitschko and then started dating Scotty McKnight. Now she’s back with Klitschko and the two are engaged.

“Very few people know, and she isn’t wearing her ring publicly yet,” adds the friend of the duo, who first parted ways in May 2011 after two years of dating.

Privately, however, the 5-foot-2 knockout and the 6-foot-6 heavyweight champ are eager to legalize their match. Says the source, “Looks like a summer wedding!”

The sex must take a lot of work. Especially since Hayden needs to bring climbing gear every time to rappel down Klitschko’s penis.
