I am doing my part to keep Courtenay Semel in the spotlight for as long as possible, just because I am certain one of these days she will do something so absolutely insane on camera that it will make it all worth it. Honestly, eventually she’s just going to snap and, like, tie Nicole Richie to a leather sofa and cover her in honey and fire ants and film the whole thing on a CoolPix camera and email it to Nikon demanding a sponsorship. She is that kind of crazy.

Here’s the former lover of Lindsay Lohan, Tila Tequila and Lord knows who else, at Sundance with her current flame, heiress Casey Johnson, whose hair seems to be recovering well from when Courtenay set it on fire earlier this month.

Courtenay Semel, the uber-rich, alcoholic, drug-addicted, but-her-faced, hot-tempered, celebrity lesbian love interest du jour, has just burned her (equally crazy) ex-girlfriend’s hair off.

CASEY Johnson – the madcap Band-Aid heiress whose father, Woody Johnson, owns the Jets – is said to be wearing her hair in a short, butch style following a vicious catfight with her ex-girlfriend, Courtenay Semel. “Casey had a fight one night with her current girlfriend,” heavily tattooed Lisa Marie Alvarez, a Los Angeles source, told Page Six. “Casey went to Courtenay’s house, and Courtenay proceeded to beat the crap out of her, and then she lit her hair on fire. Casey had to be hospitalized.” Casey’s mother, Sale Johnson, reportedly flew to LA and consulted with lawyer Robert Shapiro. No one returned calls except Courtenay, whose father Terry Semel ran Yahoo for years. “There was a fight,” Courtenay said. “But this is a major exaggeration. We are speaking. We are friends.” Casey – who isn’t speaking to her father, or her aunt, Libet Johnson – is the mother of an adopted girl from Kazakhstan.

OMG. These girls are such headcases. I swear, all the money in the world does not buy happiness. In fact, it just seems to encourage low self-esteem and crazy. The next time you think to myself, “Man, why couldn’t I have been born an heiress?” just keep these girls in mind.
