James Marsden, 39, is now a dad — again! The 30 Rock actor became a father for the third time on Dec. 14 after his former flame Rose Costa, 24, welcomed their child, a baby boy named William Luca Costa-Marsden. 

James and Rose briefly dated in 2011 after his split from his wife Lisa Linde, whom he was married to for 11 years.

He has two other children with his ex-wife, daughter Mary James, 7, and son Jack Holden, 11.

Not Together, But Supporitve

Rose fell pregnant just months after she and James broke things off last year.

Even though James and Rose are reportedly no longer together, sources say he has been very supportive — and even picked the name for the little guy!

According to the Daily Mail, rumors that Rose was pregnant with James’ baby first surfaced in June, but nothing was ever confirmed.

His On-Screen Love Life

James’ off-screen relationships seem super dramatic, but his on-screen relationship with 30 Rock co-star Liz Lemon (Tina Fey) is solid and secure. His character Cris Chross married Liz in a silly ceremony on Nov. 29, with Liz dressed as Princess Leia.

This is the last season of the hit NBC show, but Liz and Cris desperately want to be parents — character traits that both actors can relate to! Tina is the mom to two daughters: Alice, 7, and Penelope, 1.

What do YOU think of James and Rose having a kid HollyMoms?

Be honest: Did you ever think you’d see 30 Rock‘s Liz Lemon say “I do,” much less to a strapping gentleman played by James Marsden?! Of course you didn’t. Ever since the NBC comedy premiered in Oct. 2006, Tina Fey‘s character has been the über single lady — and I’m not talking about the Beyoncé kind. But all the cats of the world rejoiced Nov. 29 when Liz finally walked down the aisle in a wacky wedding to remember.

Dressed like Princess Leia — a nice call-back to the time she dressed up like the Star Wars royal to get out of jury duty a few seasons ago — Liz was positively glowing as she officially became Criss’ wife.

Mazel tov, Liz! We never thought this day would come.

The “Avatar” actress gets all potty-mouthed! while encouraging friends to donate at a Haiti benefit!

Put up or shut up, that’s basically what Zoe Saldana told friends who showed up to the Have A Heart For Haiti benefit sponsored by Heineken, Wednesday night at Palihouse in West Hollywood. The Avatar star, 31, gently persuaded her buddies the only way a determined friend knows how – by dropping a couple F-bombs! “Give whatever you can, but f–king give something, I know we can do it” she told the crowd as they cheered on her impassioned speech.

Aiming to raise funds to send to the quake ravaged country, the hostess with the mostest was a social butterfly as she took time to chat with each guest, thanking them for attending the event. Co-hosts Emile Hirsch and Avatar co-star Michelle Rodriguez scoured their rolodex for support as friends like James Marsden, Lily Collins, Gary Oldman, Marley Shelton and Topher Grace all stopped by and grooved to tunes by DJ Daisy O’Dell

“Twilight” director Catherine Hardwicke chatted with Emile, 24, who could be overheard discussing how to firm up some shooting dates as Catherine, 54, will be directing the Speed Racer star in a contemporary version of Hamlet.

T.R. Knight arrived with a female friend and bumped into former co-star Justin Chambers‘ wife, Keisha, who was solo. They had a lengthy laughter filled chat out on the patio, Marlon Wayans walked away a winner, carrying an over sized photo of a nearly naked woman on a piano, telling reporters “I’ll put this above my piano, if ever I needed more encouragement to practice, here it is”

Party goers had the chance to bid on some pretty hot items like tickets to the premiere of Twilight: Eclipse, floor seats to a Lakers game, or 3 nights in a secluded Maui resort.

The night went off without a hitch, considering –according to Zoe– it was thrown together in practically no time at all, “We like, basically put this whole thing together in 10 days, that’s why I’m so proud.” she told Hollywoodlife.com, beaming, “Its an amazingly short time for such an amazing effort. I’m so proud of everyone.”
