Last week, Kim Kardashian's blonde hair became the number one story of Paris Fashion Week.
No one was really surprised, because that's kinda what Kim does - shows up to an event and steals the show with a ridiculous style statement.
This time, however, was a bit different, as the family star of the show was supposed to be Kendall Jenner, who landed A-list Fashion Week modeling gigs with Chanel and Fendi.
Naturally, Kim's golden locks stole the spotlight, and Kendall is reportedly pissed about it.
"The whole family, aside from Kris, of course, thinks that Kim's intentions with going blonde were purely selfish," an insider tells Radar Online.
"She is supposed to be in Paris supporting Kendall, and the fact that she dyed her hair and did this drastic overhaul to one-up her younger sister is quite pathetic.
"Kim simply cannot stand anyone else in the family and she will go to any lengths to make sure it is always the Kim show, guest-starring her sisters."
The competition between Kim and Kendall has reportedly gotten so intense that Kendall is moving to London to get out from under her sister's shadow.
As for Kim's new platinum look? The insider says it's just a temporary change to help her steal Kendall's thunder.
"The blonde thing is not going to stick," says the source. "As soon as she gets back to LA, she is going back to brunette."
We're guessing even Kendall would agree that's probably the right decision.
