Scott Disick is treating girlfriend Sofia Richie to a romantic getaway in Aspen for the New Year's holiday.

According to a new report, the 34-year-old Keeping Up With the Kardashians star and father of three is going all out to make sure that his 19-year-old girlfriend knows exactly how he feels about her.

“Scott is going all out to prove to Sofia that she matters more to him than Kourtney,” a source told Hollywood Life on Dec. 29.

As the insider explained, Disick feels horrible that Richie has been shunned by his former girlfriend Kourtney Kardashian, 38, with whom he shares three kids. As fans may have noticed, Disick was not allowed to bring Richie to Kris Jenner's annual Christmas party over the weekend but his former girlfriend did bring her new man Younes Bendjima, 24, to the bash.

“Sofia is still kind of hurt over being banned from Christmas Eve and Scott feels bad. He’s going to make sure she has the most amazing New Year’s ever,” the insider noted.

Around the time that Disick and Richie confirmed they were dating, Kardashian and Bendjima went public with their own romance, which had been making headlines for months, during a trip to Cannes, France. Since then, they have been spending tons of time together in Paris and Los Angeles.

The insider noted that Disick would normally take Kardashian and their children, Mason, 8, Penelope, 5, and Reign, 3, with him to Aspen on a family trip to celebrate the New Year. However, the source noted that this year is much different, so, rather than spending time with Kardashian and their kids, he'll be partying with his younger girlfriend.

“He would normally take Kourtney and the kids to Aspen for New Year’s that’s been kind of a tradition, but this year he’s taking Sofia out of town to party instead of going with the family,” our source said. “And he’s totally spoiled her with all new snow gear, he spent over 20 grand on clothes for her. He’s proud to have her on his arm and he wants her to know that she’s number one.”

Although Kardashian has ousted Richie from her family, rumors have been swirling in regards to Richie joining Keeping Up With the Kardashians or starring alongside Disick in their own show.
