Mary-Kate Olsen & Spencer Pratt Feud Started in High School

But well before Olsen publicly dissed the villain from The Hills for being a bad-tempered high-school spoilsport on the Late Show with David Letterman Friday, the seeds of their mutual antipathy were already planted.
In a 2007 Details article about Brody Jenner, best friend Pratt brags to a reporter about how he once made $50,000 by selling a photograph of Olsen drinking at a party back when the two attended the same high school.
And Pratt's glee at his own plots doesn't end there. The other schemes he talks about include having Jenner start dating Nicole Richie and then try to get her to eat, and trying to date every girl on The Hills.
Perhaps most ironic: He spends 20 minutes talking about how he wants to make a sex video with girlfriend Heidi Montag and then post it online. It's the height of hypocrisy, if you believe Lauren Conrad's claim that Pratt started the feud between her and Montag by spreading rumors of a sex tape starring Conrad.
