Balancing her orange Hermes Birkin in one hand, and 2-year-old son Mason in the other, pregnant Kourtney Kardashian definitely has her hands full!

The hot mamma looked maternity chic in a white lace dress that showed off her gigantic bump -- she's expecting a girl this summer! -- while on a shopping trip wither her darling son in Beverly Hills, on Saturday afternoon.

Kourtney's baby daddy, Scott Disick, left his little family behind for the weekend to celebrate his 29 birthday at 1 OAK Nightclub at The Mirage in Las Vegas with friends, including Girls Gone Wild founder, Joe Francis. Thankfully Scott had a cut-out of his partner's head with him at the party, so Kourt wasn't too far from his mind!
