Washington, (ANI): Simon Cowell has reportedly withdrawn from the filming for his U.K. TV series Britain's Got Talent after struggling with a bad bout of flu. The music mogul was said to have roped in music manager Louis Walsh to fill his place on the show's judging panel while he recovers.

"Simon has been terribly sick this week. He has not stopped for months and it has all caught up with him," Contactmusic quoted a source as telling Britain's Daily Mail. “He just needs some rest and he"ll be as good as new. He has been under the weather for the past week and it was clear that he could not join the judges today," the source added.
