Z Morning Show friends and pop duo Karmin announced Monday their upcoming tour with the Jonas Brothers starting July 10 in Chicago.

There are no Maine dates, but the tour will stop in Boston at the Bank of America Pavilion on July 22.

Last fall, Karmin, made up of Amy Heidemann and Old Town native Nick Noonan, returned to Old Town High to talk to students and perform their hit "Brokenhearted."

The day before, Sabrina talked with Amy and Nick about their career.

Karmin's new single, "Acapella," has been getting good reviews, and will be available on iTunes on June 25.
