Miley Cyrus will make her European tour dates as planned, despite postponing the American leg of her tour.

The Wrecking Ball singer has been in hospital after a severe allergic reaction to antibiotics, forcing her to miss dates on her Bangerz tour which should currently be running in the US.

It has now been announced that she could be in hospital for four weeks, but as the European dates don't begin until May 2 in Amsterdam, she is expected to be back on track in time for them.

A statement from her management said: "Miley was suffering from a sinus infection during her tour in N.C. a week ago. She was prescribed the antibiotic Cephalexin which she has now suffered an extreme allergic reaction to. This type of extreme reaction can last from five to 27 days in these types of cases.

"She will remain hospitalised and is under a doctor's care until we see some improvement in her condition and is asking for your compassion and privacy at this time. Miley is devastated about missing shows and possibly disappointing her fans."

While she recovers, Miley has been posting photos from her hospital bed including a recent one of an oxygen mask with a duck's face on it which was captioned: "This hospitals full of a bunch of QUACKS (get it??? Quacks) #punnyeveninthehospy #stayinglightlovingandpositive #imissbangerztour #tryingtonotbebitter."

She also added another photo to Instagram of herself looking sad, captioned: "Over the hospital I miss #bangerztour #5amhospyselfie so sleeeeepy #medztime #wishicouldcuddlefloyd #whojinxedme."

Miley tweeted shortly afterwards: "Can't quit crying i wanna go back on tour. im meant to be onstage performing for y'all.... not laying in a hospital bed."
