Next week, it will be Toni Braxton’s turn to get VH1’s Behind the Music treatment.

The multiplatinum R&B singer (and, more recently, reality-TV star) will take a long look back at her career in the upcoming episode, discussing everything from her brushes with bankruptcy, her son’s autism, and the moment she had a heart attack on stage. And in one scene that you can preview exclusively here, she explains how she made the decision to go solo and shed her gospel image.

“My sisters were devastated,” she says, referring to her decision to leave the Braxtons — the musical family act that included her siblings Traci, Towanda, Trina, and Tamar. Only 23 at the time, Toni left her Baltimore-area hometown for Atlanta, where she’d go on to work with industry powerhouses L.A. Reid and Babyface.

Take a look at how her solo career came to be in the exclusive clip below:

Once the ball got rolling, she knew she wanted to leave behind her gospel roots and “be sexy. I wanted to push the envelope within myself.”

And the Secrets hit single “You’re Makin’ Me High” was the perfect way to go about it. “Whenever you come from a gospel background and you go secular, it is often a thought that you may go completely buck-wild,” Braxton says.

Which she sort of did: “A week before [recording ‘You’re Makin’ Me High’] I was introduced to marijuana and I got high for the first time,” she says. “And so I kinda added that in song.”Hear her tell the story herself in the following video, and be sure to tune into her Behind the Music episode on VH1 this Monday at 10 p.m.
