On the heels of their show-closing mashup performance at the 2010 American Music Awards  Sunday night (Nov. 21), New Kids on the Block  and Backstreet Boys  have announced additional dates for their joint tour as NKOTBSB  next summer.
The veteran boy bands will now begin their trek on June 2, 2011 at the Mohegan Sun Arena in Uncasville, Conn., and wrap July 9 in Vancouver. Second shows have also been added in Chicago and Toronto after the first dates sold out, according to a press release. Tickets for the new NKOTB and BSB tour dates go on sale Dec. 11 at ticketmaster.com and livenation.com.

"We can't thank our fans enough for their continued support," the supergroup said in a statement. "The love that everyone has shown to us and to this project is incredible. We can feel the excitement and we won't let the fans down. And with our new and elaborate stage design there won't be one bad seat in the house."
NKOTB and BSB performed a medley of their best-known songs -- including the former's "Hangin' Tough" and "Step By Step" and the latter's "I Want It That Way" and "Everybody (Backstreet's Back)" -- at last night's 2010 AMAs  in Los Angeles.
