Khloe Kardashian and Mason Disick: St. Patty's Day Fun!

Posted Tuesday March 18, 2014 5:59 PM GMT

Having a little St. Patrick's Day fun, Khloe Kardashian spent the holiday with her favorite little man, nephew Mason Disick.

Goofing around, the youngest Kardashian sister was laying on the ground being videotaped when the 4-year-old unexpectedly ran up behind her and whacked her with what appears to be a red hat.

Laughing after the fact, Khloe exclaimed, "Mason!" while Kourtney Kardashian's son made a run for it.

Seeming not to be angry in the least bit, the aunt-of-three uploaded the video to her Instagram page, captioning the clip, "I love being an aunt!!!! #AuntieKoKo."
