Pink has canceled her highly anticipated concert in Bern, Switzerland, due to a mystery illness.

The 44-year-old singer was set to perform at Stadion Wankdorf on Wednesday as part of her ongoing Summer Carnival Tour, but her medical team advised against it.

A statement from Pink’s team read, “It is with great regret that we have to cancel P!NK’s concert on Wednesday, 3 July at the Wankdorf Stadium in Bern. Due to illness and after a thorough medical examination, the performance has to be cancelled on doctor’s advice.”

Though the statement crushed any hopes for rescheduling the show, a source told The Sun that the show will be rescheduled as soon as possible.

The insider further explained, “[Pink] has been working so hard on the road and the performances are always high octane with loads of stunts. This, naturally, takes a toll on her and she has been advised to take a break.”

They added, “The call to cancel the gig was a hard one for her to make because she hates letting down her fans.”
