Instinct cover guy, Adam Lambert joined iconic diva, Cyndi Lauper for a duet performance of Tears for Fears' "Mad World," per La Lauper's request at Sunday's second annual "Cyndi Lauper & Friends: Home for the Holidays." The event brings awareness to LGBT homeless youth.
Adam killed "Mad World" on American Idol back in the day, so we knew we were in for a treat, but there's something even more special about watching him keep it together while he's clearly stanning out over performing a duet with Cyndi!
Definitely something to watch. Let us know what you think of the dynamic duo after the jump!
