Hayden Panettiere's giving her relationship with Wladimir Klitschko another shot!
Life & Style can reveal that the Nashville star, 23, is back together with her ex-boyfriend, 36.
"Hayden's so happy," a pal gushes to Life & Style. "They're definitely in loveagain and tighter than ever."
The pair called it quits in May 2011, but reportedly kicked off the new year with a luxe jaunt to Dubai.
"They have been traveling together," the pal reveals. "He's even planning to visit her while she films in Nashville."
"I said 'You're huge!' and he said, 'You're tiny!'" the 5-foot-2 star recalls about meeting the boxer, who measures in at 6-foot-6.
We're happy to see this couple back together!
