A rep for Cyrus says that the shows in Amsterdam and Antwerp have been delayed after the symptoms from the singer's allergic reaction return.
"After a period of improvement, Cyrus' symptoms have returned and doctors will not permit her to travel," a rep for the star said in a statement issued on Wednesday, April 30. "This type of extreme reaction can last up to 27 days and Cyrus must remain under Doctor's care at this time."
Cyrus has pushed back the concerts scheduled to take place in Amsterdam, Netherlands, on Friday and in Antwerp, Belgium, on Sunday. New dates for the two shows are expected to be announced soon. Fans now hope that the 21-year-old singer's tour will resume on May 6 at London's O2 Arena.
Earlier this month, Cyrus postponed the rest of her U.S. tour dates after she got hospitalized. The scrapped shows have been rescheduled for August. The "Wrecking Ball" hitmaker recently talked about her "scary" illness in an interview with Ryan Seacrest.
"It was so scary," she said. "I had basically been poisoning myself with something I didn't know I was really scary allergic to."
"Every two or three hours, I would be okay and then all of the sudden it would happen to me again," she continued. "It was insane. I was begging the doctors, 'Let me out to go do the show!' It was basically no way."
