(askmen.com) - Kylie Minogue walked off stage on Saturday night (13.01.07) sparking new fears for her health.
The Australian singer, who beat breast cancer last year, was forced to cut short the latest concert on her 'Showgirl Homecoming' tour, in Manchester, after just 45 minutes telling fans she was ill with flu.
However, her early exit has left her friends and family concerned she is trying to do too much too soon.
A source told Britain's The Sun newspaper: "It's awoken some of our worst fears again. There are definite concerns she has taken on too much and can't cope with this pace.
"Everyone gets flu from time to time. But during the initial months after beating cancer, it's vital to keep well.
"When Kylie announced she wanted to tour again, there was concern among her friends and family that it was too much, too soon."
Kylie, 38, apologised to the 20,000 fans at Manchester's MEN Arena for cutting the show short. The concert was her 29th show of a gruelling 33-date tour of the UK and Australia.
A spokesman for the venue said: "Kylie has a respiratory tract infection."
Doctors have advised the diminutive pop star not to try to perform again too soon. Kylie has cancelled her shows scheduled for Monday (15.01.07) and Tuesday (16.01.07) but hopes to be well enough to return to stage soon.
