Susan Boyle will not be appearing on Tuesday's episode of "Dancing with the Stars" due to illness.
As we first reported, Susan was set to sing "Hallelujah" on the show tomorrow. But a rep for the show confirmed to TMZ she won't be appearing this week -- no word yet on rescheduling.
A source tells us Susan missed a flight to L.A. today. She was supposed to tape her performance on the "DWTS" set this evening.
We're told host Tom Bergeron will address the issue on tonight's show.
UPDATE: A rep for Boyle tells TMZ, "Susan Boyle has had to cancel her performance on 'Dancing with the Stars' as her doctor advised her not to sing due to a severe throat infection. Susan is very upset at letting her fans down. Their continued support means so much to her."
