Kim Kardashian & Mason: Gotta Wear Shades

Kim Kardashian spent her 31st birthday with her favorite little man: Her adorable nephew Mason Disick!

Kim and Mason were both sporting their shades as they made their way into the Museum of Natural History in New York City today (October 21). The stylish duo were joined by Mason’s mom Kourtney Kardashian, who made a fashion statement of her own in her thigh-high boots.

Kim will be soon be jetting off to Las Vegas, where she’ll be celebrating her birthday at a party at Marquee nightclub tomorrow. So how does she feel about turning one year older? It’s “freaky,” the newlywed tells E! "I think 31 is even worse [than 30]. It's like now I'm really an adult!"
