Miley Cyrus has lamented the last month after suffering debilitating health problems.

The singer was forced into postponing a number of North America shows after suffering a severe allergic reaction to antibiotics.

She recently suffered a relapse and had to delay two European shows due to take place this weekend.

The 'We Can't Stop' lady took to Twitter to look ahead to the month of May, striking off April as "sh*t".

Cyrus said: "It's may 1st. April you were a real piece of [dog poo icon]."

The US star meanwhile is still expected to open her European Bangerz tour at London's O2 Arena on May 6.

Arena dates in Leeds, Glasgow, Manchester, Birmingham and Belfast are then set to follow.
