Meredith Vieira Friday went to work in her Halloween costume Friday, as the Today Show host was dressed as pop superstar Lady Gaga.

Vieira's Gaga get-up consisted of an ensemble similar to the space-inspired Giorgio Armani Prive dress the hitmaker wore at this year's Grammy awards, complete with blonde wig. At one point, she emerged on a stage, flanked by four beefcake dancers, and thanked her "Little Monsters" for support.
Lady Vieira wasn't the only mild-mannered Today Show personality in the Halloween spirit: Ann Curry went as Amelia Earhart, Al Roker pulled off Superman, and Natalie Morales went as another pop culture sensation, Justin Bieber.
Will Farrell and Tina Fey joined the Halloween festivities as characters from their new movie Megamind.
