Miley Cyrus Cancels Another Concert ... So Sorry, St. Louis!

Miley Cyrus is canceling yet another concert following her hospitalization Tuesday after a severe allergic reaction to medicine.

Miley took to Twitter early Wednesday morning to announce the cancellation herself, saying, "the hospital is sayin i wont b released today therefore Im not going 2 make it 2 St Louis. Im so sorry but somethings are outta my control."

As TMZ first reported, part of the reason for Miley's hospitalization was the fact she has been "off the rails" since the death of her beloved dog Floyd earlier this month.
