Kim Kardashian posted an Instagram photo of her with bleached eyebrows at little sister Kendall Jenner's 19th birthday party Monday, Entertainment Tonight reports.

The reality star captioned the photo, "About last night... #KendallsBDayParty #DontBeScaredOfMyBleachedBrows #ItsForAPhotoShoot."

The Instagram shot is of her and English fashion model Cara Delevingne.

In another photo, Kim and Cara posed next to Kanye West.

"EyebrowsOnFleek," the caption reads.

The 34-year-old reality star only bleached her brows for a photo shoot, as she clarified in her Instagram post.

Kardashian also posted a picture of her sister blowing out the candles of her birthday cake as it was actually Kendall's big day, bleached Kim eyebrows or not. For her birthday party, Kendall wore a sexy pilot outfit.

Bleaching eyebrows is a practice common for models. Both Kendall and Cara have rocked bleached eyebrows on the catwalk. Back in September, Kendall had bleached eyebrows on the runway at the Givenchy show for Paris Fashion Week. In addition, sister Khloe Kardashian's ex, French Montana, made an appearance. He is seen in a photo with the birthday girl and her mother Kris Jenner.

Yet, there are no photos of him and his ex. Khloe is in a photo with the birthday girl, however. Khloe and French Montana broke up last month, not even making it to the first year mark in their relationship. The rapper has said that he hopes they can get back together.

Before the party, the young model, Kendall, spent intimate time with her family, Daily Mail reports. She celebrated her birthday with a family lunch at Hotel Bel-Air.

Kendall's modeling career is taking off. She walked more than a dozen fashion shows this year in New York, Milan and Paris.

Khloe has gushed about how proud of her little sister she is.

"I'm so proud of her, and she's still such a good girl. She's just a goofy girl and I love that about her. I want her to stay that way," she said.
