UPDATE: See Why Miley Cyrus Is Still in the Hospital

Tough times for Miley Cyrus. It seems all that touring and partying and tongue-sticking-out can really run a girl down. Cyrus just canceled her second tour date in a week, and she's taken to Twitter to explain what's going on.

Cyrus canceled a date on her Bangerz tour in Charlotte last week, reportedly because her grief over her lost dog Floyd ran her down enough to make her sick. That illness continues this week; it seems she had an allergic reaction to the antibiotics she took last week! "Cyrus has been hospitalized for a severe allergic reaction to antibiotics and has been placed on medical rest by her doctors," the Sprint Center in Kansas City said in a statement. "She will not be able to perform as scheduled."

She then followed up with an update this morning, "I can't get a hold of my team because it is so early so I want to be the one to tell my fans especially the ones trekking to get there. the hospital is sayin i wont b released today crying cat emoji therefore Im not going 2 make it 2 St Louis.
