New Kids on the Block coming to Los Angeles with TLC, Nelly

New Kids On The Block are stepping into the ring for 2015! The pop phenoms stopped by "Good Morning America" Tuesday to announce The Main Event, a summer headlining tour featuring TLC and Nelly.

NKOTB surprised viewers with a special reveal of TLC and a personal message from Nelly, who is currently overseas with the armed forces. The groups hinted at possible collaborations while on the road this summer. The tour, promoted by Live Nation, kicks off on May 1 in Las Vegas, Nevada, and will stop in over 30 cities across North America, including Los Angeles and Anaheim.

After announcing the tour on "Good Morning America," NKOTB took over the "LIVE! with Kelly and Michael" set to step in and play a mix of super hits and new fan favorites throughout the entire hour on air.

"We always have something special up our sleeves," said NKOTB member Donnie Wahlberg. "Our fans keep asking us to come back out on the road, and we want to keep giving them what they want! We wanted to make sure it was something new and fresh and fun and totally worthwhile for all of our supporters year after year."

The tour will stop at the Honda Center on Saturday, May 2 and The Forum on Saturday, May 9.
