Kourtney Kardashian and Younes Bendjima are going strong over a year after being introduced to each other in Paris, France.

According to a new report, Kardashian and Bendjima are planning to celebrate the upcoming Christmas holiday together after the 38-year-old Keeping Up With the Kardashians star introduced her 24-year-old boyfriend to her three kids.

“It’s definitely serious,” a source close to the couple told People on Dec. 12. “No one thought their relationship would last this long, but Kourtney is very happy."

Kardashian shares three kids with her former boyfriend Scott Disick, 7-year-old Mason, 5-year-old Penelope, and 2-year-old Reign. Both Mason and Reign are set to celebrate birthdays on Dec. 14.

“Younes has met her kids,” the insider explained. “Kourtney’s family really likes him. He is the opposite of Scott. He doesn’t party, isn’t flashy and really treats Kourtney with a lot of respect. It’s obvious that he really cares about Kourtney.”

While Kardashian and Disick are quite happy with each other, her new relationship hasn't been easy for Disick to handle. In fact, during a recent episode of Keeping Up With the Kardashians, Disick flew to Cannes after threatening Kardashian, who was in town with her boyfriend. Disick then proceeded to spend time with a number of other women, including actress Bella Thorne.

Disick, 34, is now dating 19-year-old Sofia Richie.

“I got defensive,” he admitted on the show. “If you’re going to be in Cannes with another guy, like, have fun. But just know that it’s probably not going to be that fun if you run into me.”

Meanwhile, Kardashian called her trip to Cannes with Bendjima “so fun” and “freeing.”

“I’m not trying to throw anything in anyone’s face,” she said. “But I’m also not going to hide.”

Disick and his new girlfriend, Richie, haven't been hiding either and are frequently photographed together in Los Angeles and Miami. As for whether or not Richie has met Kardashian and Disick's children, that has yet to be confirmed.
