Canadian singer Celine Dion was forced to pull out of a planned duet with international opera stars Il Divo after scheduling conflicts.

The FALLING INTO YOU hitmaker was set to sing I BELIEVE IN YOU with Spaniard CARLOS MARIN, 35; Swiss Urs Buhler, 33; Frenchman SEBASTIEN IZAMBARD, 31; and American DAVID MILLER, 31, but realised she had previous commitments.

Simon Cowell's operatic group went on to record their song without her for their second album ANCORA.

Buhler says, "It was a shame, but she was the first name that came up when we discussed the duet so the fact she agreed to do the song is the main thing."
