Nashville's bad girl is getting married! That's right, it sounds like Hayden Panettiere and her boxer boyfriend Wladimir Klitschko are engaged! A source tells Us Weekly that the very few people know and she isn't wearing her ring publicly yet. Maybe that's because the two just reunited in January after breaking up in May 2011. Prior to that, the couple dated for two years. And though the lovebirds have yet to even confirm their relationship, the source also told the mag that it looks like a summer wedding is in the works!
