Report: James Marsden welcomes third child, a boy

James Marsden’s “30 Rock� character is attempting adoption with his love interest Tina Fey — but off-screen the hunky actor is reportedly a father again.

Marsden welcomed a baby boy with Brazilian model Rose Costa last week, according to People.

William Luca Costa-Marsden arrived on Friday, and while the parties are no longer an item, Marsden is said to have helped with name selection and remains “very supportive� of mom and baby.

Marsden also counts 11-year-old Jack and 6-year-old Mary with ex Lisa Linde.

Next year will see the actor help “Rock� say goodbye on Jan. 31. Toward year’s end he’ll turn up in Lee Daniels’ awards bait “The Butler,� playing John F. Kennedy alongside Minka Kelly as Jackie.

The ensemble cast also includes Oprah Winfrey, Forest Whitaker, Jane Fonda, Melissa Leo and Mariah Carey, to name a few.
