She doesn't seem too fazed!

Sofia Richie and Scott Disick took his kids out for some Christmas shopping over the weekend, and the model doesn't seem to be letting the reports about his ex Kourtney not liking her get under her skin.

The eldest K sister recently posted an Instagram of herself and her baby daddy "co-parenting" in bed together, and while it made the teen model "uncomfortable," she chose to take the high road.

"There has been and will continue to be things with Scott’s family life that bother Sofia, but she is trying to just deal without causing drama. She loves Scott and wants to be with him. She knows she will always be kind of the outsider, but she loves being around Scott and his kids. She's getting better at handling Scott’s family situations in a mature way," a source dished to People.

"She knows that Kourtney isn’t her biggest fan and she understands that. Sofia and Kourtney will never be best friends, but Sofia is happy that she has proved to Kourtney that she is great with her kids. Sofia is hoping that her relationship with Scott lasts," the source added.

We could have never predicted this romance would actually last!
