NKOTBSB Debut ‘Don’t Turn Out the Lights’ on ‘Dancing With the Stars’

NKOTBSB -- the boyband supergroup made up of New Kids on the Block and the Backstreet Boys -- took the stage on tonight's 'Dancing With the Stars: The Results Show' to perform their debut single, 'Don't Turn Out the Lights.'

Dressed in pieces of black and white clothing, the "boys" -- now a nine-piece man group -- even hit the dance floor to give themselves a little more room to strut their stuff, and the 'DWTS' dancers joined them.

But the '90s fun didn't stop there. All of the guys came back later in the show, separately (but in new outfits, of course), to give the audience a blast from the past.

First, the Backstreet Boys took the stage to perform a taste of their 1999 hit, 'I Want it That Way,' minus Kevin Richardson, who didn't get down with the idea of a rebirth. Then, New Kids rocked 'DWTS' viewers with their 1990 phenomenon 'Step by Step' -- and Joey McIntyre, a former contestant on the show, danced with a female competitor to show off a few moves he's been working on.

While the NKOTB/BSB performances took up a good chunk of the hour-long results show, former 'Idol' hopeful Pia Toscano was given the mic for a minute to show the world that she does, in fact, have what it takes to be a star -- or at least go dancing with one.
