In this special hour-long season finale of "Dress My Nest," Thom is seeing stars as he undertakes one of his toughest challenges yet--a mega home makeover for a celebrity couple! See what happens when our design guru is called on by E! News host Giuliana Rancic and her husband Bill to flip their cold condo into a newlyweds' lavish love nest. Although this bicoastal couple tied the knot last year, they've been having problems with their plush Los Angeles pad. Giuliana first bought the house as a bachelorette, but now it needs to be turned into a space that reflects both of their tastes. Can Thom help marry this couple's drastically different decorating styles? Or will he end up playing marriage counselor?
