V Snapshot: Mariah Carey Steps in for AT&T Commercial

Mariah Carey gets caught in her acting element in these candids off the set of an upcoming AT&T commercial. The larger-than-life songbird, who recently sold 168,000 copies of her new album, Memoirs of an Imperfect Angel, plays the celebrity guest whose accommodations are hooked up by a concierge's clutch 3G smartphone. Shot in New York City last month, the commercial drops this week. Check out the gallery for a sneak peek.
