Love appears to be back in the air for Hayden Panettiere and ex-boyfriend Wladimir Klitschko.

The pair, who split in June 2011 after two years of dating, were spotted kissing at the Miami Heat versus Charlotte Bobcats game in Miami Sunday.

Panettiere, 23, and Klitschko, 37, were spotted partying at nightclub Zuma in Miami Jan. 8 and a few days later the Ukrainian boxer was seen dropping the "Nashville" actress off at the airport. But Panettiere insisted to TMZ at the time that the pair were just "just good buddies."

Panettiere and Klitschko blamed distance for their 2011 split but said they would remain close friends. But they kept the PDA flowing in Miami Sunday, looking more than friends.

Shortly after Panettiere and Klitschko split, she began dating NFL player Scotty McKnight but the pair parted last December.
