He added that Sadie Grace weighed in at 7 lbs., 8 oz. A first-time mom, Applegate, 39, confirmed her pregnancy in September. The Emmy-nominated star's baby joy comes two years after she overcame a bout with breast cancer, following a double mastectomy.

Applegate has credited her baby's dad, a founding member of 90s alternative rock band Porno for Pyros, with helping keep her spirits high during her cancer battle. "I have a small but mighty support system and Martyn has really been an incredible part of my life," Applegate previously told Us.

"Without him, I don't know if I could've gone through any of it. He came around at a time when there was a lot of loss in my life on many levels, so he's been a really incredible help."

The new mom - who got engaged to LeNoble on Valentine's Day last year - tells Us she'd welcome the idea of having more kids. When asked what's on her bucket list, she told Us last year: "Babies, lots of babies. Not lots of babies, but a couple."
