Owen Wilson welcomed his second child, a baby boy, into the world this past Thursday (Jan 30th).

The 45 year-old was present while personal trainer Caroline Lindqvist gave birth. 

This is the pair's first child together but second son of Wilson's who is already a father to 3 year-old Ford from a previous relationship. 

The pregnancy news first surfaced this past October, and at the time Lindqvist was still married, but separated, to plastic surgeon Ritu Chopra.

The Swedish fitness fanatic stated at the time that she would not pursue a relationship with Wilson until her divorce was finalised or after she gave birth. 

"She is just happy that Owen is helping her out any way that he can," a source told E!News at the time, adding that Wilson was "very supportive" when she broke the news. "They have an amicable relationship and [care about] what's best for their unborn child."

"They get together for dinner and see each other fairly often," the source continued. "Owen has shown a desire to be involved with ultrasounds and doctor appointments. He's definitely invested in their unborn child."

Wilson allegedly met Lindqvist when he separated from Katie Hudson and subsequent suicide attempt in 2007, she was hired to be his personal trainer and as their friendship blossomed it evolved into "regular sex romps."

Although Wilson was reportedly happy about the pregnancy, he has no intentions of starting a relationship with Caroline, a decision which the personal trainer isn't happy with. 

Congratulations to the pair on their new baby boy!
