What's Wrong With John Mayer?

John Mayer has reportedly canceled his European shows due to a sudden mystery illness. Now we could be rude and say that the notorious singer probably pulled a sick one to go shack up with a female he developed an addiction to for the week (OK so we said it), or the singer is suffering from the cliche exhaustion. Here is an official announcement via his website:

After a sold-out performance in Copenhagen, John Mayer was forced to cancel his second show there on 5/31 due to illness. Regrettably, the illness has caused his remaining European shows scheduled through this week to be canceled as well (Amsterdam, Madrid and Manchester). Ticket holders should apply for refund from point of purchase. Mayer is returning home to the States and a full recovery is expected under a doctor’s supervision.
