Wladimir Klitschko’s week just became exponentially more memorable.

He retained his WBA, IBF and WBO heavyweight titles Saturday night by outpointing previously undefeated Alexander Povetkin and, on “Live with Kelly and Michael” Wednesday, actress Hayden Panettiere announced that she and the champ are officially engaged.

Although tThe “Nashville” star said there was no wedding date yet, it seems pretty clear that it was free-boa-constrictor-with-purchase day at their jeweler’s shop. Panettiere, 24, and Klitschko, 37,  met in 2009 and broke up after dating for two years. They got back together last spring and were, according to Us Weekly, unofficially engaged then.

“It’s like the 2.0 version,” she told Glamour magazine of dating Klitschko again. “I’ve always had great relationships and stayed really good friends with the guys I’ve dated. It blows my mind sometimes that us getting together has gotten so much attention.”
