Miley Cyrus has postponed the start of the European leg of her 'Bangerz' tour.

The 'Adore You' hitmaker has been forced to reschedule her gigs in Amsterdam and Antwerp after her on-going battle with an allergic reaction took a turn for the worse.

A statement on her website read: ''The May 2nd and May 4th Miley Cyrus 'Bangerz' tour dates in Amsterdam and Antwerp have been postponed and rescheduled for Antwerp June 20th and Amsterdam June 22nd.''

The 21-year-old singer was hospitalised on April 15 after her body rejected Cephalexin, an antibiotic prescribed for the flu, but just under two weeks later she appeared to be making a good recovery and was discharged from hospital.

However, Miley, who was forced to postpone the US leg of her tour due to the illness, has been banned from travelling by her doctor after her symptoms flared up again recently.

The statement explained: ''After a period of improvement, Cyrus' symptoms have returned and Doctor's will not permit her to travel. This type of extreme reaction can last up to 27 days and Cyrus must remain under Doctor's care at this time.''

Miley seemed less than impressed when she heard that she couldn't perform for Amsterdam and Antwerp.

Taking to Twitter on Tuesday (29.04.14), she tweeted: ''R u f**king kidding me?!?!?!?? #aprilcangof**kitself (sic).''

However, it is hoped Miley's UK gig at London's O2 Arena on May 6 will proceed as planned.
