Bennett's mom is a babe!

30 Rock's Jane Krakowski walked the red carpet at Sunday's Primetime Emmy Awards in L.A. -- her first since she gave birth to son Bennett Robert Godley in NYC April 13.

And the 42-year-old Tony winner rocked her slim, taut post-baby body in a J. Mendel Mica lightweight lame gown with pleated skirt.

Weighing seven pounds and 12 ounces at birth, little Bennett (a blond like his mom) is the first child for Krakowski and fiance Robert Godley.

"Bennett is an amazing, healthy sweet boy and we are both just crazy in love with him," Krakowski told Us shortly after Bennett's birth.

Krakowski and clothing designer Godley became engaged in January 2010; they have yet to announce a wedding date.
