Singer-songwriter Jason Mraz will be performing in all five boroughs this September, he announced yesterday.

The one-week, six-show tour begins on Sept. 17 in Brooklyn and ends seven days later with a performance at Radio City Music Hall to celebrate his latest album "YES!"

The Brooklyn Center for Performing Arts, Lehman Center for Performing Arts in the Bronx, Colden Auditorium at Kupferberg Center for the Performing Arts in Queens and Staten Island's St. George Theater will be hosting the concerts before Radio City in that order.

A ticket pre-sale began Wednesday, including "The Five Boroughs Tour Golden Ticket," which is good for all six shows.
