Owen Wilson is about to become a dad for the second time.
A rep for the 44-year-old "The Internship" actor confirmed Friday that Wilson was expecting a child with his one-time personal trainer, Caroline Lindqvist, still legally married to her plastic surgeon husband.
"They are not living together, but Owen is involved," a source told People. "He comes to doctor's appointments and makes sure Caroline is doing well."
The source added that Lindqvist didn't cheat on her husband, because they were separated when she became pregnant with Wilson's child.
"He isn't in a relationship with Caroline, nor do they plan to be in one, but he is very supportive of everything," another source told US Weekly. "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 already has a son, 2-year-old Robert Ford, with ex-girlfriend Jade Duell.
