Chris Brown -- Sorry BET, I'm Not Doing Reality TV

Don't go checking TV Guide for a Chris Brown reality show anytime soon ... 'cause the singer says it's just not his style.

Chris and Karrueche Tran were heading out of 1Oak Friday night in L.A. when we asked about BET's intense interest in signing him to a deal ... but Brown nixed the idea straight out.

We broke the story ... BET put the word out to several production companies that they badly wanted to air a reality show chronicling Brown's life after jail. They even held focus groups and prospective viewers approved.
