The sultry voice behind the 1996 hit ballad "Un-Break My Heart" is promising to get real with a new reality tv show. Toni Braxton's "Braxton Family Values" has no island getaways or dancing get-ups. She says the WE tv program will show her far-from-fantasy life and address her money and health problems. It stars Braxton and her four younger sisters, Traci, Towanda, Trina, and Tamar, the baby. It starts April 12. Tamar and Toni talked to CNN's Don Lemon about why they opened up their lives to viewers.
