Inside Hayden Panettiere's Baby Joy Over Second Pregnancy!

Hayden Panettiere is getting back to work on her hit show Nashville, but RadarOnline.com can exclusively reveal that it's on one major condition: producers write a pregnancy into the script!

Insider revealed to RadarOnline.com that Panettiere, 27, and her 40-year-old fiancé, Wladimir Klitschko, are anxious to expand their family in the coming year, especially now that she's successfully worked through in rehab the crippling post-natal depression she suffered after giving birth to their daughter Kaya in December 2014.

"Hayden's informed her bosses this is on their agenda and they're more than happy to incorporate a baby bump into the show in some way," said a source.

And the couple is planning to put the baby carriage before marriage.

"She and Wlad have been engaged for three years and have no wedding plans on the horizon at all," revealed a family insider.

"When Hayden got engaged it was implicit to her family that it would be a long engagement because she was so young. Then having their daughter kind of crept up on them before they could really plan a big ceremony," noted the insider.

"They are true partners and a very loving and serious couple, but they've gotten used to not being married — the long engagement suits them, which is why they've green-lit another baby first."
