Kourtney Kardashian was missing from Kim Kardashian‘s 43rd birthday party, but the reason why wasn’t because of their family drama. Kourtney, 44, couldn’t attend the festivities at Funke restaurant in Beverly Hills on Friday, October 20 because she’s on bed rest amidst her pregnancy, Kim revealed in her Instagram post from the party. The SKIMS founder shared pictures with all her guests, including her other sisters, Khloe Kardashian, Kendall Jenner and Kylie Jenner, and their mom, Kris Jenner, two days after the party and gave a sweet shoutout to Kourtney in her caption.
