Kendall Jenner reportedly gave Scott Disick the cold shoulder at a West Hollywood party earlier this week. The 20-year-old model was hanging out with friends at Chris Brown's listening party for his upcoming album "Royalty," when Kourtney Kardashian's ex-boyfriend walked in.

According to Us Weekly, Disick was surrounded by a large group of people including Khloé Kardashian's former beau, rapper French Montana, and a mystery brunette woman. Sources told the outlet that Jenner seemed "annoyed" when she spotted Disick and his entourage and "rolled her eyes."

"Neither of them acknowledged each other nor said 'Hi,'" the source said.

People magazine reported that after Jenner and Disick's awkward encounter at Brown's party, the model and her friends went to hang out with Justin Bieber. It's been rumored that the 21-year-old "Sorry" singer and Kourtney, 36, have been hooking up for the past few months. According to a previous report by Us Weekly, Bieber and Kourtney's fling is nothing more than a revenge hookup.

Kourtney and Disick split in July after photos surfaced of the businessman on vacation with his ex-girlfriend Chloe Bartoli. The pair has three children together, Mason, 6, Penelope, 3 and Reign, 12 months.

Kourtney and Disick's breakup has been a major storyline on Season 11 of "Keeping Up With the Kardashians." In one episode, the mom of three broke down over the split, telling sister Kim Kardashian West that she's "worked so hard" to keep her family together.

However, in recent weeks it seems Kourtney and Disick have been getting along a lot better. They were photographed earlier this month furniture shopping in West Hollywood with their son Mason, and also were spotted at a Malibu house party for celebrity Rev. Richard Wilkerson Jr.’s new book.
