Why Kourtney Kardashian Missed Kim Kardashian's 43rd Birthday Party

Kim Kardashian celebrated her 43rd birthday surrounded by her famous family and friends. However, her sister Kourtney Kardashian was noticeably missing from the festivities this weekend.

Kourtney missing her sister's party comes amid their feud on the current season of Hulu's The Kardashians. It all started when Kourtney accused Kim of "legit copying" her wedding to blink-182 drummer Travis Barker, who she's expecting a baby boy with, in Portofino, Italy for a job. And while the sisters have yet to work out their problems on their hit reality TV show, it seems like they're on good terms and the only reason Kourtney wasn't partying with her sister is because she's getting ready to give birth to Baby Barker. Kim took to Instagram on Sunday, October 22nd, to quickly explain why her sister was missing from the party. "And Kourt I’m jumping in bed with you next week for our bed rest picnic," she wrote at the end of her post.

Kim continued, "So blessed to have hit the jackpot of friends! I couldn’t have ever dreamed I would be so lucky to call these girls my friends ✨ thank you for all the birthday love ❤️." The SKIMS founder celebrated her birthday on October 21st and according to People, she took her friends and family out to Funke restaurant in Beverly Hills the night before.

The Kardashians star was joined by her sisters Khloe, Kendall Jenner, Kylie Jenner, and their mother Kris Jenner. Other guests included Hailey Bieber, Kimora Lee Simmons, Lauren Sánchez and Ivanka Trump.
