They’re thrilled about becoming parents for the first time, and Mila Kunis and Ashton Kutcher will be decorating their nursery in all kinds of pink.

According to an Us Weekly source, the “Two and a Half Men” hunk and his “Forgetting Sarah Marshall” fiancée are expecting a girl, something Kutcher knows a thing or two about.

One pal told press, “Ashton got plenty of practice with Demi’s girls” during his marriage to Demi Moore, so he’s not clueless regarding what he’s in for.

The insider added, “Mila absolutely loves being pregnant and Ashton is doting on her.” Kunis will give birth this fall.
