Poor Ashton Kutcher must be feeling awfully awkward when realizing that, by celebrating his 30th birthday a few weeks ago, his celebrity pals were exposed to Hepatitis A by an unwashed waitress who tested positive for the virus. The celebratory shindig was held at NYC’s ultra-snooty Socialista club — the same fortress we recently mentioned in light of Matthew McConaughey’s “angry chimp” dance and more:

Located in NYC’s West Village, the ironically named Cuban-themed Socialista club (Sting and Trudie Styler are investors) carries a $600 minimum tab per table, and that’s just for entrance to the first-floor cafe. Above the eatery is a lounge, not open to the public, where owner Armin Amiri shields celebrities from prying eyes. Recently, Amiri has (allegedly) used heavy-handed tactics to protect Javier Bardem from the paparazzi’s flashbulbs, including the confiscation of a photog’s memory card that supposedly contained snaps of Bardem making out with current flame Penelope Cruz.

In addition to Ashton and Demi Moore, the following celebs were in attendance: Bruce Willis, Salma Hayek, Madonna, Kate Hudson, Lucy Liu, Gwyneth Paltrow, Roberto Cavalli, Rachel Zoe, and Ivanka Trump. While these so-called A-listers scramble towards the nearest testing centres, only one thing remains certain — at the moment, Dax Shepard and Seth Green are breathing a sigh of relief that AshDog isn’t allowed to hang with the boys anymore.
