Welcome to the Big Apple!
Mason Dash Disick claps his hands — and shows off his two new bottom teeth! — after landing at JFK with mom Kourtney Kardashian on Monday in New York.
The reality star, 31, and her sisters were in the city promoting their new book, Kardashian Konfidential. The group’s press tour included stops at Today and The View, as well as Barnes & Noble for a signing.
Mason, 11 months, is Kardashian’s only child with boyfriend Scott Disick.
