ATTENTION: If you are a celebrity/common person with good connex who went to Socialista Bar on the dates of February 7th, 8th or 11th you may have been exposed to Hepatitis A! GROSS.

Ashton Kutcher celebrated his 30th birthday in style last night. Ashton and Demi first dined at the Bowery Hotel in NYC and then moved onto club Socialista, with their A-list guests following behind.  Selma Hayek and her fiance Francois-Henri Pinault showed up as well Eric Dane and his wife Rebecca Gayheart.  Single gals (for the evening) Lucy Liu, Madonna and Gwyneth Paltrow also attended.  Bruce Willis and Emma Hemming even showed up baring gifts!  Not a bad way to say goodbye to your youth!
