Owen Wilson is set to become a father for a second time, according to a U.S. report.

Personal trainer Caroline Lindqvist is pregnant with the Zoolander star's child. Editors at Us Weekly claim the pair is not a couple but will co-parent when the baby arrives.

A source tells the publication, "Owen is very involved with the pregnancy. He isn't in a relationship with Caroline, nor do they plan to be in one, but he is very supportive of everything.

"They see each other and talk often about what they want for the child. Owen is very open-minded about everything and has told Caroline he will do whatever he can."

Wilson became a first-time dad to son Robert Ford with his ex-girlfriend Jade Duell in 2011.
