Hayden Panettiere's
having a baby! 

The "Nashville" star and her boxing beau Wladimir Klitschko are expecting their first child together, Us Weekly reports.

A source close to the cute couple tells the mag that Hayden's "totally pregnant." The 24-year-old and the 38-year-old first got engaged a year ago, and have been together on-and-off for five years.

If the reports are true, this is going to throw a big wrench into "Nashville" next season, as she'll surely be showing when the show starts filming again.

It's possible they could try and hide her stomach with billowy clothing (like Kerry Washington on "Scandal"), but that's never really been Juliette Barnes' style, has it? Our guess: Her character will get pregnant ... but won't know if the kid is Jeff Fordham's or Avery's.

The blonde beauty has expressed her desire to be a mother in the past. In the May 2013 issue of Glamour magazine, Hayden said that she's ready to have kids. 

"I've lived a very big life, and I don't feel my age, and I feel like I was born to be a mother," she told the mag.

"Sometimes people speak about [having kids] like, 'Your life ends—you're never going to be able to do anything again!' And I'm like, 'What are you talking about?' Motherhood is the most beautiful, exciting thing, and there's nothing that I feel like I can't accomplish while having children in my life."

The actress also told Ellen DeGeneres last November that she thinks her children with Wladimir will be "normal height," given her tiny stature and his 6-foot-6 physique.
