We got Jessica Simpson and her BABY BUMP

Jessica Simpson's baby bump was red hot last night -- and she flaunted her new curves on the red carpet!

The mom-to-be and fiance Eric Johnson stepped out in NYC last night, where Jess was wearing a form-fitting crimson dress and matching heels.

The two stepped out to the Crosby Hotel for the Museum of Modern Art for 25th Annual Footwear News Achievement Awards -- and doesn't she look great?
