"After a sold-out performance in Copenhagen, John Mayer was forced to cancel his second show there on 5/31 due to illness," a statement on the musician's website reads. "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."
The singer has been working to restore his reputation this year after stirring up controversy with an interview in Playboy, in which he uttered the N-word, said he wasn't attracted to black women and spoke about his intimate relationship with Jessica Simpson. On Tuesday, Mayer premiered the music video for his Taylor Swift duet, "Half of My Heart," on People.com. In the clip, which doesn't feature Swift, Mayer plays up his Casanova reputation by leaving a bride at the altar.
When MTV News caught up with Mayer last year, as he was releasing his latest album, Battle Studies, he spoke about getting Swift on the track. "I woke up with the song in my head called 'Half of My Heart,' " he recalled. "And the idea is that it's this real sort of updated — not that it needs to be updated — sort of Tom Petty, Fleetwood Mac, Stevie Nicks thing."
