Christina Applegate Rolls Up To The Set In Curlers

At least Christina's rollers were green for St. Patty's Day! The actress hit the set of her NBC comedy Up All Night with her hairdo still underway ...

But hey, she's a working mom! The actress recently told Access Hollywood that her real life parallels her on-camera life, having her year-old daughter Sadie who keeps Applegate and her partner Martyn LeNoble busy.

The two have yet to tie the knot, but Christina says having a baby together is stronger than any piece of paper: "For me [getting married] doesn't add to the fact that we love each other and that we're going to be together and that we have this incredible human that bonds us for life - literally for life. So I think we're good."
