Family has always been the most important part of the Kardashian way, and yesterday (May 13) the “Keeping Up with the Kardashians” crew was spotted out for Mother’s Day Brunch.

A preggers Kourtney Kardashian, Khloe Kardashian, Lamar Odom, and Kourtney’s son Mason Disick all showed up at The Ivy to honor their matriarch Kris Jenner.

Meanwhile, Kim Kardashian was unable to make it to the big celebration, as she was scheduled for a photo shoot for Vogue Italia magazine.

Kourtney blogged, “Happy Mothers Day to my beautiful mom who teaches me so much about the world and about being a mom. Being a mom is my absolute favorite role that I have in my life and I feel so blessed to have my mother and grandmother to inspire me to be the best mom I can be. I also feel so lucky to meet and have other mommy friends who inspire me as well. I wish every mother a very special day with your children.”

And Khloe added, “Happy Mother’s Day to the funniest, kindest, most outrageous mom in the whole world — the one and only Kris Jenner! I love you mom!!!! Where would we be without you?! Thank you for everything.”
