Congrats are in order for Wedding Crashers actor Owen Wilson whose is now father to a new baby boy.

Wilson's ex-girlfriend Caroline Lindqvist gave birth to the newborn Thursday, Jan. 30, Us Weekly has reported.

While Wilson and the personal trainer broke up, an insider said that "Owen plans to be involved with the baby and help raise him."

The two dated off and on since 2003 after they met at a party. Lindqvist, 41, also recently split from her husband, Dr. Ritu Chopra, who works as a plastic surgeon in Beverly Hills.Lindqvist and Chopra were married since 2004.

Back in October another source said, "She was shocked to learn that she was pregnant but decided to keep the baby...Caroline's marriage has been shaky for years. Ritu made little time for Caroline. For years, they've lived more like roommates more than a couple."

Wilson, 44, is also father to two-year-old Robert Ford, who he had with his ex-girlfriend Jade Duell in January of 2011.

About a month after Robert was born, Wilson revealed to Jay Leno that he was named after his father.

"His middle name is Ford, he'll probably go by Ford...He's a very cute little baby boy. He's doing well. What they say about newborns not getting a lot of sleep, that's true. You look at every place as kind of a potential nap place. I'm looking at this couch like 'Maybe on a commercial break I'll get a little shuteye."

The name of Wilson's youngest child has not been released yet.
