New mom Kristin Cavallari doesn't waste any time! Just two months after giving birth to her son, Camden, the former MTV reality star is back in amazing shape -- and showing it off on the red carpet.
On Tuesday, Kristin made her first official appearance since Camden's August 5 birth, hosting ULTA Beauty's "Donate With a Kiss" event for breast cancer research and looking red carpet ready in a form fitting, black dress.
