Things haven’t been going so well for Miley Cyrus since the tragic death of her dog Floyd, and this morning (April 16) she took to Twitter to cancel another concert.

The “Wrecking Ball” babe has been laid up with a severe allergic reaction to medication that forced her to be hospitalized on Tuesday.

And regrettably she tweeted, “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."

Cyrus previously backed out of her Kansas City show, and the fate of her remaining BANGERZ tour dates is still uncertain.
