Boxing champ Wladimir Klitschko is reportedly starting to worry that his wedding with "Nashville" star Hayden Panettiere won't happen.

According to the issue of OK! Magazine, Wladimir Klitschko proposed to the "Nashville" star in October 2013 and they already have baby Kaya together, but when he opens the idea of a wedding he always gets put off.

"Wlad's starting to worry that she won't ever commit," the source told the tabloid. "Between her career and caring for the baby, she claims she's just too busy to plan anything."

"But the actress's jam-packed schedule isn't the only reason for not walking down the aisle just yet. Hayden welcomed the couple's first child, Kaya, in December, and she doesn't plan to try on any dresses until she loses 10 more pounds!" the article claimed.

According to the previous report from OK! magazine, Hayden Panettiere has been "impatient" in shedding off the post-baby weight.

"Hayden is impatient about losing the pounds-and eager to have her figure back before awards season-he's not letting her go to extreme measures to get back in Hollywood shape," the article said.

Wladimir Klitschko, meanwhile, has allegedly been helping his wife shed off the baby weight but the boxing champ wants to do it the healthy way.

Wladimir Klitschko and Hayden Panettiere welcomed baby Kaya on Dec. 9, 2014.

In an interview with Entertainment Tonight, the boxing champ credited the "Nashville" star for being an amazing mom. He also talked about the wedding.

"Now is for now -- when people get married there are different things they promise to each other and I understand the promising part, but I think [having] children is something that connects you until the end of your days no matter what," he said.

"And I think that, Kaya, our daughter, has connected us forever. And that's the most amazing thing. Everything else is coming, it's something that needs to be planned ... but as I said, the connection with the child is better than any marriage!"
