George Michael is putting his faith in his doctors.
The British hitmaker has been forced to cancel a concert tonight at London's Royal Albert Hall after his physician advised him to rest his ailing voice which has been hampered by a viral infection.
"A doctor visited George this afternoon and confirmed he is suffering from a viral infection and has a high temperature," reads a venue-issued statement.
The "Careless Whisper" singer says the break will allow him time to recover before a Friday show set for the Royal Albert Hall.
"He is disappointed that he cannot perform tonight's concert, but he has been advised to rest," says Michael's publicist. "He received a tremendous reaction from the audience last night and is very sorry that he has had to postponed."
Promoters are asking fans with tickets for tonight's gig to hold on to them as it's hoped the singer will schedule a makeup date.
Michael launched the U.K. portion of his 47-date Symphonica tour Tuesday accompanied by a 41-piece orchestra and performed a slew of Wham! and solo hits as well as his tribute to Amy Winehouse, a cover of "Love Is a Losing Game."
Lots of fluids and rest, George, and you'll be ready to go-go real soon.
