WENN 1 / 11

It's no secret that Brandi Glanville is a lightning rod for how she acts and what she says, but she may have gone too far on an episode of "The Real Housewives of Beverly Hills" when she took a dig at a 17-year-old.

The reality TV-star's controversial comment came as her friend and fellow housewife Yolanda Foster questioned Brandi about her drinking.

"You're saying, ''Am I an alcoholic?'" Brandi asked Yolanda, before retorting with a slam about Yolanda's model daughter Bella Hadid, who was busted for DUI in July 2014. "You've heard that about your daughter, and she's not."

Bella is now 18, but was 17 at the time of the filming.

Painfully, Brandi wasn't done with the jabs either. "That's what people have been saying lately," she said about Yolanda's daughter. "And she's not, and you know it, she only made a mistake."

Predictably, Yolanda didn't take too kindly to the attack.

"I mean here we go -- you're now personally attacking me about my daughter while I'm just trying to help you as your friend," she said.

Lisa Rinna, another fellow cast member, felt the questioning of Brandi was fair.

"She's an addict," she told her co-stars "I've seen enough of addiction where I go, ''Oh my God, if she wanted to straighten up her life and change her whole paradigm she needs to get clean.'"
