Sisters Khloe and Kourtney Kardashian were in attendance, naturally taking to Snapchat to document all the highlights from Rob's festive fête. The two were all decked out in St. Paddy's Day gear, including green hats and glittery glasses.

At one point, Kourtney's 7-year-old son, Mason, even jumped in for a silly snap with aunt Khloe!

The picture was taken just a few moments before Khloe, Kourtney, Mason, sister Kylie Jenner, mom Kris Jenner and ex-fiancée Blac Chyna cheered Rob on as he blew out the candles on his custom-made cake. The sweet treat featured an adorable throwback of Rob, dressed as Peter Pan.

Later in the night, they were treated to a private screening of the new Disney live-action film, Beauty and the Beast.

Rob also got in on the social media sharing, posting a pic of his silver, green and gold balloons, which spelled out, "Happy Birthday Rob."

And although he appeared to be having a blast at the party, he said the "best gift of all" was his daughter, baby Dream.

It doesn't get much better than that!
