Christina Applegate, 39 is a mom! The talented actress, producer and her fiance Martyn LeNoble, 41 welcomed a baby girl according to a spokesperson:

“Actress Christina Applegate and fiance, musician Martyn LeNoble, welcomed daughter Sadie Grace LeNoble on Thursday, Jan. 27, 2011, in Los Angeles,” “Mother and daughter are doing great.”

The actress and LeNoble have been together for three years and got engaged Valentine’s Day last year (although she was spotted with an engagement ring a few months prior).

Christina successfully battled cancer when in August of 2008 she had a double mastectomy after finding a lump in one breast.

Congratulations to the happy couple. Christina will make an amazing mother!
