Norfolk-based Ann Blanchard, who was a body guard for Whitney Houston during the early 1990s, painted a picture for a local television station of the singer’s life before drug abuse.

“She was a classy woman. She gave her all,” the Norfolk resident told ABC 13 about Houston on Sunday. “She was a very sweet, genuine person.”

Blanchard adds that Houston didn’t do drugs or “do anything inappropriately,” but noticed a change when Houston’s now ex-husband Bobby Brown entered the singer’s life.

“I told my friends back in 1991 ... she likes bad boys and I’m afraid that’s not going to be a good thing for her.”

Houston died Saturday at 48, and the cause of death was still unknown Monday afternoon. DCist has a roundup of Houston’s last D.C. appearances, including stops in 1994 and 1997, here. Video of the full interview with Blanchard is after the jump:
