Happy birthday, little guy!

On Friday, Kim, Khloe and Kourtney Kardashian got together to help celebrate her son Mason's third birthday in Miami. He's a growing boy!

Kourtney's baby girl Penelope, along with Scott Disick, joined in on the festivities as the family first went to Gold Coast Railroad Museum before dining at Serendipity afterwards. We bet he just loved all the attention!
