Madonna, Demi Moore, Bruce Willis and Gwyneth Paltrow are among hundreds of patrons of a New York bar being advised to get a Hepatitis A vaccination after it emerged that a barman working at Ashton Kutcher's recent birthday bash might have passed the liver disease onto them.
Kutcher celebrated his 30th birthday with a host of A-list stars at New York's Socialista club on Feb 7, 08.
Now, the New York health department has issued a statement, warning anyone who visited Socialista in Manhattan's West Village on Feb 7, 8 or 11 to get a vaccination.
The celebrities have been warned that there's a possibility they might have contracted the liver disease from the bartender, who worked at the bar on Feb. 8 and Feb. 11.
'Any patron who visited the establishment after 8pm on February 7th or 8th, or after 10pm on February 11th (the times the infected person worked after becoming infectious), is considered to be at risk and needs a preventive shot,' The Daily Telegraph quoted the health department, as saying.
Other celebrities reported at the bash were Ivanka Trump, Liv Tyler, Catherine Keener, Lucy Liu , Salma Hayek, Javier Bardem, Eric Dane, Rebecca Gayheart and fashion designer Roberto Cavalli.
Socialista was not immediately available for comment, nor were representatives of Moore, Kutcher or Madonna.
