Kerry Washington, who just announced that's she's pregnant (yay!),  will host this weekend's episode of "Saturday Night Live." The actress, who earned an Emmy nod for her role on the hit ABC series "Scandal," has never hosted a sketch comedy show before, but there's a first time for everything. Eminem will be the show's musical guest and make his sixth appearance on the show to promote his new album "The Marshall Mathers LP 2," which will be released on November 5.
