[lastfm]John Mayer[/lastfm] may be known recently for all the A-list stars he’s dated, but that’s not what made him famous.

The singer is currently on tour in Europe and has just announced that he has cancelled a slew of dates due to an illness.

 He posted the following message on his website: “After a sold-out performance in Copenhagen, [lastfm]John Mayer [/lastfm]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.”
