"Being pregnant is wonderful," Kate told Extra while promoting her film Something Borrowed. "You do get the pregnant mush-brain... you know what it's like? It's like getting stoned."

But Kate has remembered to take the advice of her doctor and keep her cravings in check.

"My doctor looked and me and goes, 'So let's try not to gain 68 pounds this pregnancy,' " Kate said adding she told her doctor she wasn't "promising anything."
