Adam Lambert’s Dec. 17 outdoor concert on Jimmy Kimmel Live! has been canceled, an ABC spokesperson confirmed to EW. “We decided not to move forward with the booking at this time,” said the spokesperson, who wouldn’t comment on whether the cancellation had anything to do with the singer’s controversial performance at the American Music Awards last month on ABC. Lambert’s appearance on Kimmel was booked before the AMAs had aired.

Lambert’s rep told EW that the singer will now perform on The Jay Leno Show on Dec. 21 instead, but a rep for the NBC show was unable to confirm his appearance at press time.
