B. Scott -- an openly gay transgender person -- is suing BET, claiming the network humiliated him during the recent BET Awards by yanking him off the show because he was wearing women's clothes.
Scott claims in his lawsuit -- obtained by TMZ -- he was hired to be the Style Stage Correspondent for the pre-show in June. At the beginning of the show, Scott claims he was wearing a flowing black tunic and black pants ... which he says were approved by BET honchos.
Scott claims after the first segment of the pre-show, he was pulled backstage and told his garb wasn't acceptable. Scott says he was ordered to "mute the makeup, pull back his hair" and remove the women's wear ... which included heels.
Scott says they forced him to change into men's clothing [see below]. Nonetheless ... Scott says he was still 86'd from the show and replaced by Adrienne Bailon.
Scott says he was humiliated and suffered damage to his reputation, claiming BET is guilty of discrimination based on gender identity as well as sexual orientation.
He wants $2.5 million minimum from BET.
