The heckler caught on tape harassing Bristol Palin at a bar last fall is apparently suing Lifetime for putting the altercation on her new reality show.
She was riding a mechanical bull when Stephen Hanks began heckling Bristol Palin, yelling, "Did you ride Levi like that," "Your mother is a whore," etc.
Palin confronted him, asking if he didn't like Sarah because he is "a homosexual." Things got headed, but afterward, Hanks apologized to Palin.
But now he's suing for defamation, invasion of privacy, intentional infliction of emotional distress and misappropriation of right of publicity.
Hanks' attorney, Michael Gulden, says no one ever asked Hanks to sign a release for the footage to be used on Bristol Palin: Life's a Tripp.
The video (above) has been online ever since the altercation and has been viewed nearly a million times. Still, he's seeking damages in court.
"He felt this was the only way he could protect his rights," Gulden says, adding, Hanks was "simply a patron at the bar" where this went down.
Lifetime says it has "no comment" because it is a legal issue.
Bristol Palin's new show, which she says shows a "normal" and "grounded" side of her, premieres Tuesday. Check out some Life's a Tripp photos.
