Lily Allen was hospitalized on Wednesday, May 7, when she came down with a particularly nasty case of the flu. "#SHEEzUS in #SHOSPITAL. I'm fine though guys, just need some fluids cause I can't keep anything down. #dramz," she posted on Instagram. It's clearly been a busy couple of days for the 29-year-old British singer, who attended the Met Gala on Monday in New York City, and made a guest appearance on the popular British show Alan Carr: Chatty Man just hours before landing in the hospital.
