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!
