Kristin Cavallari shopping Beverly Hills pregnant

Kristin Cavallari is such a busy mamma-to-be!

The reality star had that pregnancy glow as she stepped out in a slinky jumpsuit to do some shopping and pick up some grub, before making her way to a gym in West Hollywood, on Friday afternoon.

Cavallari was in the middle of planning her big wedding to on-again finacé, Jay Cutler, last month when she suddenly found out she was expecting!

Now the former Hills star is putting her wedding plans to the Chicago Bears player on hold until after she has the baby, telling Celebuzz. "I’m not even looking for a wedding dress right now. I’m pregnant! I’m not going to go try on wedding dresses."

Sounds like Kristin may have to wait until 2013 to finally have her Big Day!
