Actress Hayden Panettiere, 23, is reportedly ready to walk down the aisle with her off-and-on boyfriend, 37-year-old Ukrainian boxer Wladimir Klitschko. The duo split a while back, but reconciled back in January because they thought it would be worth a second go.

Now, according to a source for Us Weekly, they are in the midst of planning a wedding that'll take place this summer.

"Very few people know, and she isn't wearing her ring publicly yet," said a close friend of the couple, who first broke up in May of 2011 after a two-year courtship.

Regardless, the petite actress refuses to confirm that they're even back together, despite the fact that the pair was spotted smooching at a Miami Heat game on March 24.

She claims they're “just good buddies” -- but if that's how Hayden treats all her male pals, her dance card must stay pretty full.
