Miley Cyrus 'Can't Quit Crying' In The Hospital

After a severe allergic reaction, Miley tweets frustration over cancelling more Bangerz Tour dates.

Miley Cyrus is "over the hospital," and we don't blame her. The pop star has been lying in a hospital bed since Tuesday after reportedly suffering a "severe" allergic reaction to antibiotics.

The illness has forced her to cancel at least two shows on her Bangerz Tour, in Kansas and St. Louis.

The concert cancellations have made Cyrus a very unhappy patient. The singer has been vocal about her disappointment, posting a photo of herself in the hospital on Instagram early Thursday morning (April 17) with the caption, "I miss #bangerztour #5amhospyselfie so sleeeeepy #medztime," and a few more hashtags about wishing she could cuddle with her recently deceased dog Floyd, and another asking who jinxed her with all of this bad luck.

Cyrus also hit Twitter to further vent her frustrations writing, "Can't quit crying i wanna go back on tour."

As to what landed Cyrus in the hospital in the first place, a rep for the "We Can't Stop" singer told E! News that she "was suffering 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," adding that this "type of extreme reaction can last from 5 to 27 days in these types of cases."

According to the rep, Miley will remain hospitalized until her condition improves. She is said to be "devastated about missing shows and possibly disappointing her fans," but that was clear from her status updates.

Cyrus is next scheduled to hit the stage Friday in Nashville, with the U.S. leg of her tour wrapping up next week on April 25. There has been no word on whether Miley's illness will force her to cancel more shows.
