"Best night celebrating you @letthelordbewithyou 📌 an amazing soul. we all love you very much," Sofia wrote to her Instagram.
Scott also took to Instagram to commemorate the occasion, sharing a photobooth reel of him and Sofia.
Although Kourtney was in attendance at the party, she did not post a birthday tribute for her ex. The two split in 2015, but have co-parented together since.
Earlier in the day, Kris Jenner wished Scott a happy birthday with an Instagram collage, calling him the "most incredible father to Mason, Penelope and Reign.”
Kim and Khloé Kardashian also joined in on sending sweet tributes to the father of three, both sharing photos of him on Instagram.
“Found these gems from 2008,” Kim captioned a photo of a young Kylie and Scott together.
“Scott I’ve known you for almost 15 years, we’ve all been through so much together and have the best memories!” she added. “You are like my brother. I’ve seen you grow up and become the most amazing father and friend. So happy you are in our lives. I love you Happy Birthday @letthelordbewithyou.”
