Miley Cyrus has been forced to postpone two more concert dates, this time in Europe.
The 21-year-old pop singer's May 2 date in Amsterdam and May 4 appearance in Antwerp, Belgium, on her Bangerz tour have been pushed back to June.
A news release said the star's symptoms from a severe allergic reaction to antibiotics have returned and doctors will not allow her to travel.
Miley was forced to postpone her US tour until August after treatment for a sinus infection went awry, but expected to be able to keep her European tour on track. The news release said she still expects to make her London appearance on May 6 as planned. The Antwerp show has been rescheduled for June 20 and the Amsterdam concert will be held on June 22.
