For the next challenge, the finalists are each assigned a different holiday party - St. Patrick's Day, Cinco de Mayo, Mardi Gras, New Year's Eve, or Easter - and take turns planning and hosting their own holiday special. Special guests, <strong>Tia Mowry</strong> and <strong>Donal Skehan</strong>, are on hand to help <strong>Giada De Laurentiis</strong> and <strong>Bobby Flay</strong> taste the food and judge the holiday specials.
