Singer Lily Allen has been admitted to a hospital due to dehydration after a severe bout of vomitting.

The singer's promotional schedule for her third album "Sheezus" seems to have taken its toll on the singer, reports femalefirst.co.uk.

Allen began feeling ill upon returning to Britain from a short stay in New York for the Met Gala Monday, and she was taken to the hospital Thursday as she suffered from dehydration.

She took to Instagram to share a photograph of herself lying on a hospital bed with a drip attached to her arm.

Allen captioned it: "SHEEZUS in Hospital. I'm fine though guys, just need some fluids cause I can't keep anything down (sic)."
