And it came from Twitter, so it MUST be true!

After partying hard at Trousdale last night, Lindsay Lohan posted the message above on her Twitter account. After the word got out that Lindsay was making nasty accusations, Sam denied the incident, tweeting, "Guess what didn't happen tonight......"

And Miley Cyrus' ex (we're assuming she means Justin Gaston)?! C'mon Linds, don't get him involved in this mess!
