Jennifer Garner and Ben Affleck welcomed their third child this week, according to sources. Is it a girl or a boy?

Jennifer Garner and Ben Affleck have a baby boyJennifer Garner and Ben Affleck welcomed another child into the world, according to several sources. The parents of Violet, 6, and Serephina, 3, are now dealing with a new challenge: a baby boy!

Baby boy Affleck was born in Santa Monica, California according to People. The couple — married since 2005 — knew the sex of their baby, but refused to give more details. Many figured they would have another girl — and that would have been fine with Affleck.

"I would have thought [he wanted a boy]. At first... I really thought so," the former Alias actress told Jay Leno earlier this year. "And then [Ben] kind of said, 'Well, we have girls. We know how to do girls. My girls love me. I'm the big guy in the house.' So, now I'm not sure."

They haven't released the name of their new son, but Garner joked that they considered a Disney theme for the family addition.

"[They suggested] Donald Duck, Minnie Mouse Affleck," Garner told Leno. "And then they moved on... [to] Peter Pan, Captain Hook, Smee."

Reps for Garner and Affleck haven't responded to requests for comment.

We can't wait to see pictures of the baby — he's sure to be a happy baby, based on how smiley his two sisters are all the time. Who wouldn't be happy with parents like Ben and Jen? Especially since they're teaching their children how to be responsible citizens.

"I got to a point in my life where I felt like I had been very fortunate," Affleck told People of the Eastern Congo Initiative he started in 2008. The actor just returned from his eighth trip to the war-torn African nation.

"And I wanted to do something more with my life than just make movies and try to make money. I wanted to do something that was important to me in other ways and would serve as an example to my kids."

Affleck and Garner teach their kids through example, he said.

"I tell them it's important to be involved in the world in ways that help others and not just yourself."
