It's been a rough few weeks for Miley Cyrus and on Tuesday (April 15), she suffered another setback.

According to her rep, a "severe allergic reaction to antibiotics" landed the talented twerker in the hospital.

Having to cancel her concert in Kansas City, Miley tweeted, "Kansas I promise Im as [heartbroken] as you are. I wanted so badly 2 b there 2night. Not being with yall makes me feel shittier than I already do."

Later, the 21-year-old star posted a selfie in her hospital gown with an octopus toy and the caption, "Mr. Octopussy & some amazing Drs are taking good care of me."

Last week, the "Wrecking Ball" singer had to cancel her Charlotte show due to the flu, while she was already having a rough time mourning her dog Floyd's death.
