MySpace plague Tila Tequila smooches Yahoo CEO spawn

What is it, precisely, that is so annoying about the on-off romance between MySpace-MTV fameball Tila Tequila and Courtenay Semel, the daughter of former Yahoo and Warner Bros. bossman Terry Semel?

The dotcom heiress is best known for being Lindsay Lohan's first same-sex fling, before the actress hooked up with Sam Ronson and Semel moved on to Tequila. (She's also got a violent streak, and swears like a venture capitalist!) She showed up at a Los Angeles Borders for a book signing to promote Hooking Up With Tila Tequila. (With that title, shouldn't Semel herself have been the author?)

Socialite Life has a clip that's sure to leave you diabetic. "She's not here to beat up any fans," Tequila explains. "I'm just here to get my book signed," says Semel. Then they coo and hug and kiss, all for the cameras. Interviewed alone, Semel says she attended the event "to support my girlfriend" and that "she couldn't put the book down, for somebody with, like, major ADD problems ..." ADD problems? It's a mystery why her dad never got her a job at Yahoo. She would have fit right in.
