After doing a joint tour with the Backstreet BoysNew Kids on the Block proved that they're all for helping '80s and '90s kids get in the nostalgic mood. The classic boy band will keep up their throwback appeal with a massive 2015 summer tour alongside TLC and Nelly. Holy flashback, indeed.

The band announced The Main Event tour on Good Morning America alongside TLC's Rozonda "Chilli" Thomas and Tionne "T-Boz" Watkins. "That's a lot of hit records in one night, I'm excited," NKOTB member Joey McIntyre said. "It's going to be one big, huge, massive party."

"We are bringing with us the biggest girl group in the history of music—TLC," added Donnie Wahlberg. "This is such a great bill and we have so many hit records and such huge followings that we just want to make it the party of the year. That's why we call it The Main Event. It's going to be the event of the year."

Walhlberg then showed even morelove for the classic R&B outfit by pledging $10,000 to the group's Kickstarter-funded final album. He added one stipulation with his donation: "You have to do a duet with us." Get ready.

If you're not coming for the classic hits ("Step By Step," "No Scrubs," "Country Grammar," hello!!!), come for the once-in-a-lifetime duet. Scroll down for the full tour dates.
