Toni Braxton is in love -- and her family can't stop teasing her about it.
Only ET has an exclusive sneak peek of Thursday's episode of Braxton Family Values -- in which Tamar, Towanda, Trina and Traci Braxton make fun of Toni for gushing about her relationship with rapper Birdman.
"You don't have to sell anything. Your boyfriend is number five on the Hip Hop Forbes list," Tamar teases Toni during a family lunch. "She knows she can have anything she wants to, because he's rich."
Toni's sisters continue to rib her about her relationship, but it's their mother, Evelyn, who goes in deep.
"When you're in love, you just turn into a fool!" she says as her daughters laugh, making jokes and high-fiving each other at the table.
"I think that Toni perhaps is in love. I see that smile on her face, the way she lights up," Evelyn says to the camera. "You know, love can be a wonderful thing."
"I know my family is getting a little annoyed with me, but somehow I can't shut up," Toni admits in her confessional. "I'm just happy right now!"
