30 Rock's James Marsden welcomes his third child

Handsome 30 Rock Star James Marsden, 39, has welcomed his third child — his first with Brazilian model Rose Costa, whom he dated after separating from his wife Lisa Linde in 2011.

Rose gave birth to their baby boy last Friday, December 14, in LA, California. And the name is...

William Luca Costa-Marsden.

Baby William joins James's two children with Lisa — Mary James, 7, and Jack Holden, 11.

Congrats to the family!

Love! xo Haley-O
