Real Housewife Calls Rehab Roommate Lindsay Lohan a 'Slob.'

On Real Housewives of Vancouver, Christina Kiesel is portrayed as a booze hound who enjoys a night with a fine red as much as she does a fine man. But in a new interview with, the recently single reality star opens up about her lifelong battle with depression, which eventually led her to check into Promises -- the Malibu celebrity rehab centre where, she claims, she sobered up alongside a bald Britney Spears, made out with a pop singer and became bunk buddies with a 20-year-old Lindsay Lohan.

"I had major depression, so I thought I'd give it a go," Kiesel recalls.

In 2007, the future Housewife checked herself into what she calls an "adult camp, which just happened to consist of Britney Spears with her shaved head."

Kiesel says that she only spent two days with Spears but recalls the newest X Factor host "likes to drink orange juice when she's scared."

When Spears departed, Kiesel claims she found herself matched up with another famous troublemaker.

"Right after [Spears] left, Lindsay Lohan checked in and was my roommate," she recounts. "She's actually a really nice girl -- a complete slob, clothes everywhere -- but nice."

Despite the tabloid fodder around her, the "horny" Kiesel admits she had other things on her mind.

"I did make out with a couple famous people -- that's what people do in rehab," she laughs. "You know who is really cute and sweet? The singer Howie Day, we collided -- soberly. "

Five years later, the self-proclaimed 30-year-old confesses that, though she enjoyed her time at Promises, she still suffers from the disease.

"Unfortunately, you can't twelve-step your way out of depression," she sighs.
