Toni and Tamar Clash In Extended ‘Braxton Family Values’ Trailer

I've been there before. You're a new artist. Toni Braxton and her younger sister, Tamar, are clashing divas on the forthcoming season of "Braxton Family Values."

In an extended trailer released by WE, the sisters come together to record a Gospel effort only to clash over the sound and direction.

"I think that's corny. It's too dated," Toni Braxton says of a song in the clip below. "I'm an old b*tch. I've been doing this a long time. You're a new artist. I don't wanna be there. I've done that!"

"Braxton Family Values" premieres Thursday, August 14 on WE.
