Two years after the birth of his first love child, OWEN WILSON’s at IT again!

The 44-year-old “Wedding Crashers” star is secretly preparing for the January birth of his child with 41-year-old Swedish-born fitness trainer Caroline Lindqvist, who’s in the process of getting a divorce from Beverly Hills plastic surgeon Dr. Ritu Chopra and has reportedly been separated from her husband for more than a year.

Owen already has a 2-year-old son, Robert, with former girlfriend Jade Duell.

The screen star met Caroline shortly after his 2007 suicide at­tempt, which was sparked by his split from Kate Hudson. At that point, he hired Caroline – who currently works in real estate in Malibu – to be his personal trainer.

Their friendship evolved into regular sex­ual romps, says a family friend, and both are reportedly thrilled that they’re expecting a son together.

“Caroline broke the news to Owen this past May shortly after confirming that he was the father,” said the friend.

Although her representative emphasized that she was already separated from her husband, the friend said: “A few days later she filed for divorce from her husband.

“Caroline begged him for a quiet, hassle-free divorce, and he obliged.

“Neither has hired an attorney, and Caroline is going to walk away from the divorce with practically nothing. But she is going to score big time by having Owen’s baby – she’ll be set for life.”

On Aug. 26, 2007, The ENQUIRER was the first to report that the “You, Me and Dupree” star was rushed to Saint John’s Health Cen­ter in Santa Monica, Calif., after he took an overdose of prescription pills and slashed his wrists at his home. We revealed that he was despondent after seeing photos of Kate, who had dumped him, cuddling with a new boy­friend, comedian Dax Shepard.

Owen and Kate briefly rekindled their ro­mance a few months later, but it didn’t last. He went on to date a string of gorgeous wom­en, and The ENQUIRER exclusively reported that Jade, a federal air marshal, was pregnant with his baby. She gave birth to their son on Jan. 14, 2011, at Owen’s Maui estate. The two reportedly split up five months after the baby was born but remain on good terms.

Late last year, Owen bought Jade and little Robert a $1.4 million house in the Mar Vista area of Los Angeles, not far from his Santa Monica residence.

“Owen was dreading telling Jade about Car­oline being pregnant because she can be a real spitfire when she gets angry,” the friend said. “Jade was shocked, but she kept her cool, at least for now.”

The one thing Jade has requested, says the source, is that Caroline not give birth at Owen’s home in Hawaii.

“That’s where Owen and Jade’s son was born and she wants it to stay special just for them,” explained the friend. “Owen is not sure what Caroline wants to do, but he’ll support her decision, whatever it is.

“In any case, he’s going to have to figure out how to keep the peace between these two women so he can continue to be a good dad.”
