The singer, who was taken to hospital last week after collapsing, was due to play before the legends in Germany on Monday.
However, the Daily Mirror says doctors decided she would have trouble flying and performing following the scare, which was reportedly down to drink.
It is also unclear if she will play at this weekend's V Festival in Essex and Staffordshire.
A spokesman for the band said: "She has just pulled out of the concert. That is all we know."
A source at her record label, asked if she would play the V Festival, commented: "I don't know."
