When it comes to reality TV, “public humiliation” goes with the territory.

Big Rich Texas star Pamela Martin Duarte has hit one of her castmates with a lawsuit. As Breaking Celebrity News previously reported, the blond socialite has accused Bonnie Blossman Myer of leading “a cyber-bullying campaign to defame her.”

She also accuses Bonnie and another woman – Dena Miller who is not on the show – of planting negative stories about her in the media.

But Pam may have a tough road ahead with the suit, Breaking Celebrity News has exclusively learned.

A confidential agreement that all the cast members have to sign -- and seen by Breaking Celebrity News -- states that the “artist acknowledges that the program may consist of opinions and/or statements about, or conduct affecting artist, made by or engaged in by other participants or other people connected with the show."
