Why Brandi Glanville wants to kill herself with booze?

REAL Housewives of Bev­erly Hills” beauty Brandi Glanville is so obsessed with ex-husband Eddie Cibrian and his new wife LeAnn Rimes that she could end up killing herself with booze, warns an ex-lover.

In a bombshell exclusive ENQUIRER interview, TV talk-show host John Kerwin spoke with amazing candor about the bizarre date he had with the troubled reality star last December. He also revealed that the 40-year-old mother of two is dangerously fixated on her longtime enemy LeAnn, who slept with Eddie while he was still married to Brandi. “If LeAnn gets pregnant, I’m convinced Brandi will try to drink herself to death,” Kerwin told The ENQUIRER. “She really needs help.”

The TV personality made his shocking comments following Bran­di’s recent headline-making night of partying at a Hollywood hotel. After stumbling in front of photographers, the boozed-up former model suffered a major wardrobe malfunction – flashing her black thong and exposing a breast. She later Tweeted: “I got drunk with my (gay friends)…

Everyone kept sending us drinks. I was being polite.” Shortly before last Christmas, Ker­win, 40, had an even wackier night out with the out-of-control beauty. As the two dined at a restaurant, Brandi seemed “very upset,” he re­called. “Every time she talked about LeAnn she had more wine. She said LeAnn is like an angel fish because ‘she sings like an angel and drinks like a fish.’ It was so hypocritical.

“Later, we went to her home where she made drinks and turned on ‘Housewives’ so we could watch her on TV. She looked at herself with such love – she was just mesmerized by her image on the screen. When I told her she looked beautiful, she got really aggressive sexually. She per­formed oral sex – twice – which included her bit­ing me ‘down there.’”Upset, Kerwin says he slept in the guest room after being “a breath away from having in­tercourse.” Later, he was enraged to learn that she had a sexually trans­mitted disease she never told him about even though she’d previously admitted it in her book “Drinking and Tweeting.”Fumed Kerwin: “It made me furi­ous. She’s a trashy narcissist!”
