Hayden Panettiere has lined up her next big role: mother-to-be.

The “Nashville” star, 24, and fiancé Wladimir Klitschko are expecting their first child, reports Us Weekly.

“Hayden is totally pregnant!” an insider told the magazine.

The actress and the heavyweight boxer, 38, started dating in 2009 before breaking up in 2011. Last year they reunited and soon announced plans to wed.

Impending motherhood won’t slow Panettiere’s thespian ways, though. The critically acclaimed “Nashville” was just renewed for a third season by ABC.
