Aretha Franklin has canceled a Detroit-area performance set for July 27, citing ongoing treatment.
Franklin was born in Memphis, Tenn., but was raised primarily in Detroit and considers it her hometown.
The show at DTE Energy Music Theatre in Clarkston, Mich., a Detroit suburb, initially had been scheduled for June 22 but Franklin postponed it to later this month.
In a letter written by the Grammy-winning singer and distributed Friday by her publicist, Franklin then said she was canceling the show "one last time" due to an unspecified ongoing treatment.
The 71-year-old Queen of Soul had announced in May that she was putting off scheduled performances in Chicago and Connecticut to undergo medical treatment.
