Lindsay Lohan attended Sean Penn’s private dinner for "Milk" last week at The John Dory restaurant in NYC, and according to Fox News, the actress got very cozy with the film's star!

Sources say Lindsay showed up sans girlfriend Samantha Ronson, and immediately slid into a seat next to Sean. According to a source for Fox News, the two "nuzzled” before taking off, presumably for an after party.

Was Lindsay simply being friendly towards the Oscar-winner, or is there something else going on here?
