Just call her Mrs. Claus!

Kourtney Kardashian got into the holiday spirit with an ugly Christmas sweater and Santa hat to go toy shopping for her kids yesterday, and we don't think we've ever seen the mother-of-three this happy! She's usually a sourpuss, but she couldn't stop smiling as she left Toys R Us with a ton of gifts in her basket. Her brood is a lucky bunch!

Rumor has it the eldest K sister has invited her boy toy Younes Bendjima to spend X-mas with her family, but she's banning Scott Disick from bringing Sofia Richie around.

"Kourtney made it clear to Scott that his girlfriend Sofia is not allowed at any family holiday events. Kourtney has several issues with Scott dating Sofia and does not like it at all. Kourt has banned Sofia from meeting the kids despite how serious things are getting between Sofia and Scott. Kourtney is also trying to prevent Scott from bringing Sofia to the big annual Kardashian family Christmas party. Kourtney wants to maintain family tradition and she does not think Sofia fits into that ideal," a source dished to Hollywood Life.

"The disagreement over significant others came to a head with an epic explosion between Scott and Kourtney. They had a huge fight and Scott made it clear to Kourtney that he feels the same way about her boyfriend Younes as she does about Sofia. Scott has argued with Kourtney that if Sofia is not allowed around during Christmas then the same goes for her man Younes. Scott feels that Kourtney‘s demands are unfair and so he is pleading with her to follow her rules on tradition too," the source added.

We wonder if she got any toys for her 24-year-old beau?
