WEST HOLLYWOOD (CBS) — An angry bargoer who faced off with Bristol Palin at Saddle Ranch bar and restaurant last year is now suing the reality TV star for defamation, according to TMZ.

The encounter between Palin, 20, and 47-year-old Stephen Hanks was caught on tape by HOLLYWOOD.TV and posted on YouTube in September.

The then 20-year-old daughter of former Alaska Gov. Sarah Palin had just fallen from a mechanical bull while filming her new reality show when she was heckled by Hanks.

Hanks, who says he never signed a waiver, is angry that his image is being used in advertisements for the new Lifetime show, “Bristol Palin: Life’s a Tripp”, according to TMZ, which also reports that he’s suing Palin and Lifetime’s parent company, A&E, for unspecified damages.

The following conversation between Palin and Hanks can be viewed in the above video:

“Did you ride Levi like that? Your mother is a whore! Your mother is a f***ing devil!” he shouts.

Palin approaches the man and asks, “Is it because you’re a homosexual and that’s why you hate her?”

“Pretty much … and why’d you say I’m a homosexual?” he responds.

“Because I can tell you are,” Bristol says.

“You’re f***ing white trash from Wasila!” he screams as she leaves with her production crew. “F*** you, you f***ing b***h!”
