Sorry, Adele fans. The British singer is canceling her North American tour because of her laryngitis. Earlier, the 23-year-old singer postponed five dates on the tour, but she is now canceling the remaining nine shows. In a statement, she said she was “really frustrated” but "there is absolutely nothing I can do but take the doctor's advice and rest some more." Her latest album, 21, is the bestselling album of the year, and her single “Rolling in the Deep” is No. 1 on Billboard's top 100 charts. She said she's looking into rescheduling the tour.
