KANSAS CITY, MO (AP) -An ailing Miley Cyrus canceled her concert Tuesday night at Sprint Center after she was hospitalized.
The notice came a matter of hours before she was scheduled to go on stage, and it was crushing news to her legions of fans.
"I'm devastated. Like, I shouldn't be laughing. I want to cry. We just kind of looked at each other, and my eyes started watering, and I was like 'no, I don't believe it,' and everyone was like, 'hey, you know it's canceled,'" said Sophie Lewis, who had come to Sprint Center with her friends.
A press release from the Cyrus camp said the cancellation is because the performer is in the hospital.
"Cyrus has been hospitalized for a severe allergic reaction to antibiotics, and has been placed on medical rest by her doctors. She will not be able to perform as scheduled," according to the release.
On her Twitter account, Cyrus said "amazing doctors" are taking "good care of me" and she shared a picture of her with a stuffed animal in her hospital bed.
She also used emoticons to express her disappointment to concert goers.
"Kansas, I promise I'm as (heartbroken) as you are. I wanted so badly 2 b there 2night. (crying face). Not being with y'all makes me feel (expletive) than I already do," she wrote on her Twitter account.
In recent days, Cyrus has tweeted about having a fever, cough and sore throat.
Fans feel sick themselves.
"This was going to be the first time I would have seen Smiley in concert. And we had 19th row seats, which is pretty close. So I'm pretty mad," was the reaction of ticket holder Erin Kiely.
"Mixed emotions. Just want to cry, but at the same time, loving Smiley and wanting her to get better," was the take of fan Hannah Davis.
According to TMZ.com, Cyrus fell ill at the Sprint Center in downtown Kansas City where Truman Road was filled with buses for her Bangerz tour. She's said to be in a Kansas City hospital.
TMZ said she had been shopping with her mother earlier in the day while in town.
Earlier this month, Cyrus' beloved dog Floyd died and she canceled a concert in Charlotte just 30 minutes before it started.
At the time, Live Nation said the 21-year-old pop singer had been diagnosed with the flu and was ordered to rest.
Cyrus became a star of the Disney show Hannah Montana. Her concert at the Sprint Center several years ago sold out in a matter of minutes, and became the subject of City Council meetings regarding scalping of tickets. But her decidedly adult antics of late, including twerking at the MTV movie awards, and her tumultuous personal life, have made headlines and tarnished her squeaky clean image.
