It's Halloween at the Megan Show! Our set is completely decorated and everyone is in costume! Megan welcomes a big Halloween fan, Neil Patrick Harris, from How I Met Your Mother. Then, it's Mr. Britney Spears himself–Kevin Federline! Kevin tells Megan about his guest appearance on CSI, and then performs "Privilege," off his debut album Playing With Fire. In honor of the holiday, some very scary animals drop by the set. And, for those procrastinators, Robyn Moreno from Woman's Day has last minute costume ideas for kids.
