When James Van Der Beek announced via Twitter March 13 that his wife Kimberly Brook had given birth, the actor left out one important detail: his newborn son's name!

Two weeks later, the Don't Trust the B—- in Apt. 23 actor's rep confirms to Us Weekly that Van Der Beek has named his baby boy Joshua. The newborn joins older sister Olivia, 18 months.

When Us spoke to Van Der Beek in 2011, the actor admitted that fatherhood was like nothing he ever imagined.

"You know what surprised me the most? I was prepared for it to be a lot of work, but if anybody would've told me how much fun it would be, I would not have believed them," he said. "People always say, 'It's the best thing you'll ever do,' but I always thought they meant 10 or 20 years down the road when you'd be like, 'I'm glad I had a kid.' But moment to moment, it's really the most fun I've ever had."

"Of course there are a lot of sleepless nights, but it just surprised me how much fun it all is," the actor, 35, told Us. "You can't really communicate that to someone who doesn't have a kid."

Prior to marrying Brook, 30, in August 2010, Van Der Beek was wed to actress Heather McComb from July 2003 through March 2010. The Dawson's Creek alum's new show, Don't Trust the B—- in Apt. 23, premieres April 11 on ABC.
