George Michael was forced to pull out of his scheduled gig at the Royal Albert Hall on Wednesday night after developing a "virual infection" and "high temperature" at the last minute. 

The star was meant to perform to a London crowd, at what would have been his second show at the legendary venue on his Symphonica tour, on October 26, but had to sit it out on doctor's orders. A spokesperson for the singer apologised on his behalf and said:

"He is disappointed that he cannot perform tonight's concert, but he has been advised to rest. He received a tremendous reaction from the audience last night and is very sorry that he has had to postpone".

Michael tweeted a message to his fans on October 24 that explained he was "resting" his voice for the capital city's performances:

"In London, not speaking to anyone till tomorrow, resting my voice for the Albert Hall wanna be perfect for my fellow Londoners. :)"
