Kim Kardashian is said to be "jealous" of the relationship between her daughter North West and Kanye West's new wife Bianca Censori.
The SKIMS founder, 42, has been open about her struggles co-parenting with her ex-husband and a source has said his new marriage has thrown "another wrench" in the works.
Kanye and 28-year-old Bianca tied the knot in a private ceremony back in January and the Yeezy architect has since been seen getting close to her husband's family.
