Miley Cyrus blasts unkind critics from sick bed

Miley Cyrus has lashed out at mean critics from her sick bed after an allergic reaction forced her to postpone another date on her Bangerz tour.

The Wrecking Ball singer has been angered by all the negativity directed towards her in social media circles after she fell ill and had to be hospitalized.

The singer axed a concert in Kansas City, Missouri on Tuesday night (15Apr14) and she has since postponed a gig in St. Louis, Missouri on Wednesday (16Apr14).

The cancellation, Miley's third so far on the Bangerz tour, appears to have upset fans and critics alike, who have taken to Twitter.com and Facebook.com to take aim at the pop star.

In a furious post on Wednesday, Cyrus tweets, "humans can b so selfish. if any1 (anyone) thinks id rather b layin n a (be laying in a) hospital bed than doing what i love on stage theyre f**kin LAME. im miserable (sic)."
