John Mayer has cancelled gigs across Europe after falling ill in Copenhagen, Denmark.
The singer/songwriter performed at the city's Forum Copenhagen venue on Sunday (30May10) and was due to play there again on Monday (31May10), but he was struck down with a mystery illness and has jetted back to the U.S.
A statement on his website reads, "After a sold-out performance in Copenhagen, John Mayer was forced to cancel his second show there... 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).
"Mayer is returning home to the States and a full recovery is expected under a doctor’s supervision."
Mayer's next scheduled show is in North Carolina on 17 July (10). No further details of the rocker's illness were available as WENN went to press.
