Jessica Simpson  put her postbaby body on display, donning a short black skirt to celebrate a friend's birthday in Santa Monica on Friday night. Jessica was joined by her fiancé, Eric Johnson, as well as her best friend, CaCee Cobb, and CaCee's husband, Donald Faison, at the birthday bash. Both Jessica and CaCee welcomed newborn sons recently since Jessica gave birth to her baby boy, Ace Knute, on June 30, while CaCee and Donald welcomed their son, Rocco, more recently on Aug. 15. Jessica gave us a first look at Ace  on the cover of Us Weekly last month, but we have yet to sneak a peek at CaCee's little one.
