Popsugar Celebrity Celebrity Families Scott Disick's 36th Birthday Party Pictures Scott Disick Celebrates His 36th Birthday With Sofia Richie and the Kardashian-Jenner Clan 28 May 2019 by Monica Sisavat Solís First Published: 27 May 2019 View this post on Instagram Best night celebrating you @letthelordbewithyou 📌 an amazing soul. we all love you very much A post shared by Sofia Richie (@sofiarichie) on May 27, 2019 at 2:06am PDT Scott Disick celebrated his 36th birthday on Sunday, and naturally, it was a whole Kardashian-Jenner affair! Kourtney, Khloé, Kylie, and Kim all attended the festivities, along with girlfriend Sofia Richie and his and Kourtney's three kids, 9-year-old Mason, 6-year-old Penelope, and 4-year-old Reign. Sofia documented the bash on her Instagram stories, which included temporary tattoos, lots of flowers, a black-and-white themed cake, and clothing from Scott's Talentless line. While the idea of having your girlfriend and ex-girlfriend at your birthday party may seem a little awkward for some, Scott and Kourtney know that coparenting is all about balance. Back in December 2018, Kourtney poked fun at her family dynamic with a silly Instagram snap and later joined Scott and Sofia on holiday in Mexico. Scott and Sofia have been dating since late 2017, and the father of three recently revealed on an episode of Keeping Up With the Kardashians that Sofia is totally understanding of his relationship with Kourtney. "Sofia knew going into this that I was extremely close with Kourtney," Scott said. "She was like, 'Listen, I will never get between you and your family and your children. Just speak to me and make me comfortable.'" See every photo from Scott's fun-filled bash ahead!
