The song -- written by Ne-Yo and Afrojack, also defendants -- has a line: "Hustlers move aside, so I'm tiptoein, keep flowin' / I got it locked up like Lindsay Lohan."

Lindsay is pissed, claiming in her lawsuit ... "the lyrics, by virtue of its wide appeal, condemnation, excoriation, disparaging or defamatory statements by the defendants about the plaintiff are destined to do irreparable harm to the plaintiff."

Lindsay, who claims in the lawsuit she is "a professional actor of good repute and standing in the Screen Actors Guild, is suing under the New York civil rights laws, which protects people from having their name exploited for commercial purposes.

Lindsay alleges the appearance of her name in the song "causes [Lindsay] to be associated and identified in connection with defendants."
