Miley Cyrus was hospitalized for a severe allergic reaction to antibiotics, according to Sprint Center in Kansas City, where she was to perform her "Bangerz" show Tuesday.
Cyrus "has been placed on medical rest by her doctors. She will not be able to perform as scheduled. Refunds for tickets will be available at the point of ticket purchase. Tickets purchased online or by phone will be automatically refunded," the center said in a statement.
"Kansas I promise Im as as you are. I wanted so badly 2 b there 2night. Not being with yall makes me feel sh***ier than I already do," she tweeted. "Mr. Octopussy & some amazing Drs are taking good care of me."
Details on her condition were not immediately available. She had earlier this week tweeted about a recurring fever and cough.
Earlier this month, Cyrus' beloved dog Floyd died and she canceled a concert in Charlotte, N.C., 30 minutes before curtain time. Concert promoter Live Nation said that Cyrus, 21, had the flu and was ordered to rest.

It was not immediately clear if she would miss additional shows because of the hospitalization.
