Kim Kardashian attends Kendall Jenner's birthday party with bleached eyebrows

This was sure to raise some eyebrows.

Kim Kardashian showed up to sister Kendall Jenner's 19th birthday party Monday sporting bleached brows with her dark brown locks.

The 34-year-old reality starlet shared a snap alongside model Cara Delevingneand revealed her lighter look was for a photo shoot. 

"About last night... #KendallsBDayParty #DontBeScaredOfMyBleachedBrows #ItsForAPhotoShoot," North West's mama wrote.

Kim shared the shocking snap along with a series of others after sister Khloe Kardashian revealed in an interview Monday that the brunette beauty may not have been invited to the soirée.

"We're going to go to a family lunch, and then later tonight Kendall's having like 15 people over for a little girls' party. I don't know if it's even a party, but a girls' gathering," Khloe Kardashian told People magazine earlier in the day at the launch of HPNOTIQ Sparkle in Beverly Hills.

"I asked Kim, 'Oh, are you going tonight?' and she was like, 'I didn't know Kendall was doing anything!'" she said.

"I don't know if she was late to be invited, but I'm invited, so I feel good about that!"

While Kardashian claimed the affair was a "girls party," it looks like her ex-beauFrench Montana stopped by.
