Miley Cyrus is ill once again!

The 21 year-old singer has been forced to cancel two more shows from her 'Banger' tour after symptoms from a serious allergic reaction returned, E!News reports.

Last month Cyrus postponed the remaining dates of her US tour after being hospitalized for suffering an allergic reaction to antibiotics she was taking on April 15th.

After a week of receiving treatment from doctors, Miley was finally released on April 24th and the European leg of the tour was expected to continue as planned, but her health quickly deteriorated.

The 'Wrecking Ball' singer has now cancelled her sold-out concerts in Amsterdam and Antwerp that were scheduled for this weekend.

But her show on May 6th in London is still expected to go ahead.

A statement addressing Cyrus's health read, "Cyrus is continuing to recover from the severe allergic reaction she suffered on April 15. After a period of improvement, Cyrus' symptoms have returned and Doctor's will not permit her to travel."

It continued, "Cyrus must remain under Doctor's care at this time. The London date at O2 Arena will proceed as planned on May 6th."

On Tuesday (April 29th), the songstess tweeted 128 crying cat face emojis, which can only be a reaction to her health taking a turn for the worse once again.

"I was on this medicine for five days-everything was all good-and on the sixth day, I just woke up and it was so scary," the 'We Can't Stop' singer recall. "When you're allergic to something, you're basically poisoning yourself, so I had just basically been poisoning myself with something I didn't know I was really scary allergic to. It was so scary."
