Lindsay Lohan has confirmed that Sam Ronson is her girlfriend.

Last night, Lindsay Lohan and Sam Ronson were partying at the Ultimate White Party at the Shrine nightclub inside MGM Grand’s Foxwoods, and when it was Sam’s turn at the DJ booth, Lindsay took over the announcing duties. An eyewitness told OK! Magazine that, “When the lights came out, she announced Sam and said, ‘And no she’s not single.’”

Later that night, Lohan was heard protesting, “My girlfriend won’t play my songs!”

So there you have it, Lindsay has officially called Sam her girlfriend. What a surprise. Even with all the pictures of them together, I would have never guessed they were a couple. Yeah, right! Come on Lindsay, just release an official public statement already.
