Kourtney Kardashian pregnant Beverly Hills

Kourtney Kardashian arrived at a friend's baby shower in Beverly Hills yesterday in a colorful maxi-dress, while Kim stuck to her usual black.

While we didn't get a chance to snap Kim arriving, she did Tweet a photo of her and her assistant and the reality star seems to have added a new accessory to her collection -- a knuckle duster reading "KimYe!"

You think it was a gift or did she buy it for herself?!

Meanwhile, Kourtney's baby daddy Scott Disick babysat their son Mason, treating him to lunch in Beverly Hills. Guess baby Penelope stayed home with the nanny!
