As the baby of the family, Tamar Braxton is prone to acting a bit spoiled -- and by a bit we obviously mean a lot. Tired of singing back-up to big sister Toni, she stormed out of a discussion about making a family record on the season premiere of 'Braxton Family Values' (Thu., 9PM ET on WE).

Tamar has been focusing on putting together a solo release, and is ready to be a star in her own right. But it was when their mother, Evelyn, stepped into the argument that Tamar stormed off, and Evelyn took that as a personal slight against her.
