RUMORS have circled that Kim Kardashian is “jealous” of the relationship between her daughter and Kayne West’s new wife Bianca Censori.

While North is clearly a fan of her new stepmom, a source has told Star Magazine that Kim Kardashian is not.

“It gets under Kim’s skin,” they revealed.

Separations are never easy, especially when kids are involved.

According to Natalie Costa, 40, a children’s confidence and parent coach and the founder of the London-based organization Power Thoughts, the feelings of jealousy that Kim is experiencing are very common among separated parents.

“Whilst you naturally want your child to be happy, be safe, and to get along with their new stepparents, it is also normal if feelings of jealousy arise,” Natalie told The U.S. Sun.

“Jealousy comes from a space of fear and worry that something will be taken away from us. It comes from a protective space – wanting to protect what’s important to you,” she added.

Kim, 42, who co-parents her three children with Kayne, has previously opened up about her struggles with him since their divorce, saying that co-parenting is “hard”.

A source close to the Skims founder has revealed that his marriage to Australian model Bianca has thrown “another wrench” in the works.
