UPDATE: Wilson's rep has confirmed the baby news.
You know the father. Now meet the other parent!
Owen Wilson is expecting a baby with his about-to-be divorced personal trainer, Caroline Lindqvist, a source confirms to E! News. The actor is also dad to 2 1/2-year-old son Ford from a previous relationship.
We're told that Lindqvist and Wilson are not currently in a relationship but that the Midnight in Paris star has known about the pregnancy for several months and is "very supportive" of her.
"They get together for dinner and see each other fairly often," the source says. "Owen has shown a desire to be involved with ultrasounds and doctor appointments. He's definitely invested in their unborn child."
According to the source, Lindsqvist is going through a divorce with her plastic surgeon husband, but does not plan on pursuing a relationship with Wilson after her split is finalized or after the baby is born.
"She is just happy that Owen is helping her out any way that he can," the insider adds. "They have an amicable relationship and [care about] what's best for their unborn child. They are both excited to have a baby."
A rep for Wilson hasn't yet returned a request for comment.
The 44-year-old star welcomed son Ford on Jan. 14, 2011, with then-girlfriend Jade Duell. He most recently reteamed with Vince Vaughn for The Internship and appeared on an episode of Comedy Central's Drunk History and is due back on the big screen Dec. 5 in the comedy You Are Here.
