If last week’s inaugural MixTape Festival proved anything, it’s that boy bands are back and here to stay. Mixing the old with the new, boy-band nostalgia reached new heights after the Wanted, 98 Degrees, New Kids on the Block and the Backstreet Boys shared the stage for the first time.

But after the good news came the bad when supergroup NKOTBSB (New Kids on the Block and the Backstreet Boys) closed out the festival, telling fans it may have been the last time two groups share a stage for quite some time.

But when MTV News caught up with New Kids on the Block, they said they weren’t ruling out a possible get-together down the line. In fact, Jordan Knight said he hopes there will be “a long, long string of shows” with the Backstreet Boys.

“We had too much fun and we wish them the best,” Joey McIntyre added. “Kevin [Richardson]’s coming back. I think they’re working on a record. This door is wide open, our relationship is like a barn door. It’s just blown to pieces.”

“NKOTBSB, it’s like another group,” Donnie Wahlberg said. “Every now and again we say, ‘Hey, New Kids was fun, let’s go do NKOTBSB’ because that’s our other band.”

Well, now that they are taking a time-out from NKOTBSB, New Kids are now focusing on releasing their own material, their first since 2008’s The Block.

“We are actually walking into the studio as we speak,” McIntyre said. “We’re excited to make some new music and keep it fresh for us and the fans.”

Wahlberg added, “Joe’s on a songwriting frenzy.”

Their last album, which debuted at #2 on the Billboard 200 Charts, featured a host of collaborations including Lady Gaga, Ne-Yo and the Pussycat Dolls, but according to McIntyre, their latest effort is collaboration-free.

“No guests, no guests — that’s the name of the album, no guests allowed. Except for our fans,” McIntyre joked. “We really can’t afford any guests,” Wahlberg added, laughing. “We have a low budget.”

All kidding aside, according to Knight, NKOTB will “for sure” have the album out in 2013.
