Miley Cyrus has been like the energizer bunny for the past few months.  Non-stop touring, red carpets, and promotional events can take their toll though...and that is exactly what has happened to Cyrus.

According to sources, Cyrus may have been rushed to the hospital because of an allergic reaction to antibiotics.  TMZ reports that the reason she was on the meds was because she wore herself down by hard partying and an emotional meltdown over the death of her dog.

She has been "an emotional mess" since Floyd (Cyrus' dog) died earlier this month.  TMZ was told Cyrus has had crying fits and has been unable to sleep because of her loss.

Sources close to TMZ say that Cyrus' escape has been partying.  "She's been off the rails since this happened," writes TMZ.  Apparently, Cyrus has been drinking a lot, and drugs are also involved.

Those close to Cyrus claim she was on medication because she was sick from being extremely worn down.

Whatever the fact may be, we hope Cyrus feels better soon (and that drugs are not involved).  

Miley posted the photo below on her Twitter account.  She captioned the pic: "Mr. Octopussy and some amazing Drs are taking good care of me."



Update: Miley tweeted that she will NOT be released from the hospital today; this is the second show the singer has had to cancel.
