Hayden Panettiere and Wladimir Klitschko are preparing for baby no.2, just four months after her first daughter, Kaya, was born. Meanwhile, the heavyweight champion will try to shake off the rust as he faces Bryant Jennings at the Madison Square Garden on April 25.

According to OK! Magazine, the heavyweight champion "loves being a dad and wants to start trying again ASAP."

Hayden Panettiere is reportedly hesitant to have baby no. 2 so quickly because, "She's just finding her footing as a mom.

However, the report said that the "Nashville" star does want a big family, just like Wladimir Klitschko, so baby no. 2 is not as far off.

As Wladimir Klitschko prepares for baby no. 2, he has a looming challenge ahead in Bryant Jennings later this month as he fights again on US soil for the first time in seven years.

"If HBO ratings for Klitschko vs Jennings are sky high, we may partially attribute its success to Klitschko's growing interest among fans of Hayden Panettiere and the hit TV show Nashville," Fight Saga reported.

The website also posted a rhetorical question, "If you're a Nashville viewer but not a fight fan, are you more interested in the career of Wladimir Klitschko today than you were two years ago?"

Meanwhile, Celebrity Dirty Laundry noted that Wladimir Klitschko is almost 40 years old so if he and Hayden Panetierre are planning to have baby no. 2, they should start right away "or else her future husband could be changing diapers in his 50's."

"The Nashville writers wrote Hayden's first pregnancy in to the show's current storyline. But, anyone that is familiar with Hayden's character Juliette knows how much of a diva she is - and writing a second pregnancy for the country music singer in to the show would be a stretch," CDL said.
