The singer has been under the weather this week and took some antibiotics that made her allergic.
Miley Cyrus was rushed to hospital after suffering severe allergic reaction to some antibiotics she was taking. The "Wrecking Ball" singer was hospitalized on Tuesday, April 15 and therefore was not able to perform in Kansas City as scheduled.
"Cyrus has been hospitalized for a severe allergic reaction to antibiotics and has been placed on medical rest by her doctors," a statement from Kansas City's Sprint Center read. No replacement date has been announced yet.

She also posted a photo of her on hospital bed holding a toy octopus. "Mr. Octopussy & some amazing Drs are taking good care of me," she captioned.
Cyrus has been ill in the past few days. She tweeted on Monday, April 14, "I woke up like disssss #SICK," adding, "Fever fever go away." She has also canceled her concert that day in Charlotte due to flu.
