New Kids on the Block staged a nine-minute Battle of Boston with New Edition on Sunday’s American Music Awards, the first time the two Celtics-and-Red Sox-loving groups have ever shared a stage.

They are following it up with the addition of two more dates on their MixTape Tour 2022: Rosemont, Ill.’s Allstate Arena on 6/18 and Boston’s TD Garden on 7/16. Tickets for the new dates go on sale Tuesday; fan club presales begin today.

Promoted by Brad Wavra of Live Nation and booked by CAA’s Darryl Eaton, the tour, opened by Salt-N-Pepa, Rick Astley and En Vogue, is now up to 57 arena shows.
