Miley Cyrus has been hospitalized and placed on bed rest by doctors after having a "severe reaction to antibiotics."

Cyrus, who is currently on her "Bangerz" tour, had to cancel her Kansas City concert Tuesday as a result of her illness. She also had to cancel a show in Charlotte, NC last week due to the flu.

Though in the hospital, Cyrus isn't too ill to tweet to her fans.
