Hayden Panettiere kissing Wladimir Klitschko - guess they're back together?

hayden-panettiere-wladimir-klitschko-kissing.jpgRumors have been swirling for a couple months that actress Hayden Panettiere and her ex-boyfriend Wladimir Klitschko are back together. Now they've gone rather public with their displays of affection.

TMZ has the pictures of the "Nashville" star kissing the Ukrainian boxer at the Miami Heat-Charlotte Bobcats game in Florida on Sunday (March 24). The two previously dated for two years, but ended things in 2011.

Panettiere has previously been linked to NFL players Scotty McKnight and Mark Sanchez, "Heroes" co-star Milo Ventimiglia and "One Tree Hill" star Stephen Colletti.
