Kourtney Kardashian and Scott Disick might be co-parenting for their kids and in their respective new relationships now. However, she still sets strict rules and regulations for her ex-boyfriend and baby daddy when it concerns their children.

The 38-year-old Keeping Up With the Kardashians star reportedly doesn't want Disick's girlfriend Sofia Richie around her children. As fans already know, Kardashian and Disick share three children, namely 8-year-old Mason, 5-year-old Penelope, and 3-year-old Reign.

According to Hollywood Life, Kardashian asked Disick to refrain from bringing Richie around her children because she feels their relationship won't be long-term.

"Kourtney does not like the influence Sofia has over the kids and she does not want the kids getting attached to someone that Kourtney feels will not be around or a part of their lives very long," a source close to Kardashian explained.

The source further added that the reality star isn't too fond of Richie playing stepmom to her children because she fears the impression she will leave on the kids.

Is Sofia Richie Trying To Be Kourtney Kardashian?

Recently, an insider revealed that Kardashian was starting to get creeped out by the model's transformation throughout her relationship with Disick and feels that she is trying to steal her look. The mother of three supposedly believes that Disick is behind Richie's new look and is probably manipulating her.

Those that follow Richie on Instagram know that she was originally sporting blonde hair prior to dating Disick and kept the color for some time while they were together. However, in December 2017, the 19-year-old took to Instagram to debut her brunette tresses.

Kardashian's alleged accusations might not be too far off as the model was mistaken to be Kardashian while out with Disick and was presumed to be stealing one of her looks.

On Thursday, March 15, the two were spotted leaving Barneys New York in Beverly Hills, California. While on a shopping errand, Richie wore a black button up top with cut-off jean shorts with black sunglasses and black booties. The father of three, on the other hand, wore a beige sweatshirt with jeans and white sneakers.

Kourtney Kardashian's Beau

Although Kardashian doesn't want Richie around her children, she lets new beau Younes Bendjima around them. The couple has been together for almost a year now and sources close to the reality star claims she's happiest she has ever been.

As previously reported, the pair began dating in 2016 and Bendjima actually helped to translate for the Kardashian family during Kim K's robbery incident that took place in Paris.
