Kim Warns Kylie - Stop Living My Life!

The reality stars’ sibling rivalry is spinning right out of control.

It’s a rivalry that’s been simmering for years, but now tensions have exploded between Kylie Jenner and Kim Kardashian!

Yep, sources tell NW the power siblings are fighting over everything from their cosmetic brands and rapper baby daddies Kanye West and Travis Scott, to baby names.

And it’s turning into one of the ugliest feuds in the clan’s history – which, given their notorious penchant for dramz with a capital D, is no mean feat!

“It seems everything Kim does, Kylie can do better, and she’s not afraid to push that point home,” spills an insider. “It’s bad enough that their partners are both rappers, but when Kylie lords it at the Grammys with Travis, it annoys Kim to no end.”
