Celebrities Demi Moore, Ashton Kutcher and Madonna are among hundreds of patrons of a New York bar being urged by New York health officials on Thursday to get a Hepatitis A vaccination after a bartender was found to be infected.

The city health department issued a statement for anyone who attended Aston Kutcher’s 30th birthday bash. This scare, of course, could end Madonna’s famous streak of three weeks without contracting a communicable disease. Asked about the scare, Madonna said, “Blimey, that lot’s a bunch of filthy buggers. I’ll absobloodylutely get the doctor to check under the bonnet.”
