The two Broadway stars, who are also best friends, get tired of being so sweet and occasionally like to show their other sides, the New York Post reported.
So the two are appearing as TastiSkank, otherwise known as "the smokin' love child of the Indigo Girls and Tenacious D."
Dressed in pink high heels and miniskirts, they are singing their own compositions, drawn from real-life experiences, including "We Don't Do Threesomes" and "I (Heart) Dirty Boys With No Money."
Cast members from their two shows are expected to turn out.
"Just don't expect show tunes!" Reinders said, the Post reported.
