British singer Lily Allen took to Instagram Thursday to share a selfie from a hospital bed following her hospitalization over her self-diagnosed "projectile vomiting." "I'm fine though guys, just need some fluids cause I can't keep anything down," Allen captioned the picture. Before being rushed to the hospital on Thursday morning the "Hard Out There" crooner tweeted that she couldn't stop "projectile vomiting" and felt dehydrated. The night before being hospitalized Allen, 29, appeared on on Alan Carr's comedy show Chatty Man.
