Now Look at Me! Watch Laura Benanti Strip Down to Katy Perry's 'Part of Me' with The Skivvies at 54 Below

She's glowin’, oh whoa, indeed! Laura Benanti was the latest Broadway guest of honor to join Lauren Molina and Nick Cearley (together known as The Skivvies) for an undergarments-only concert on November 9. Tony winner Benanti, in her second scantily clad collaboration with The Skivvies, showed up in her sexiest red-hot onesie to sing a mash-up of Katy Perry's "Part of Me," Destiny’s Child "Independent Women" and Alicia Keys' "Superwoman." Of course, Benanti was sparkling! A firework! A dancing flame! You won't ever put her out again. Check out the star’s hot and hilarious performance below!
