Kendall And Kylie Cut All Ties With Sofia Richie

The blossoming romance between Scott Disick and Sofia Richie is doing more than just raising eyebrows — according to a source, it’s caused Kendall and Kylie Jenner to cut ties with the 19-year-old model.

“The girls grew up with Sofia, so to them, it’s beyond disrespectful that she’s swooped in on Scott,” the source explains,

adding that the sisters are “taking it personally” because Scott, 34, is “like a brother to them — it makes no difference that he and Kourtney Kardashian are over.”

It doesn’t help that Sofia also dated Kourtney’s former fling Justin Bieber, 23.

“They’re beginning to think Sofia has some sort of obsession with Kourt,” says the source.

“But even if it’s just coincidence, they’re always going to side with their sister.”
