Audrina Patridge earned $10,000 to attend a party at a San Diego nightclub. Her The Hills cohorts Spencer Pratt and Heidi Montag would likely laugh in their face, since they claim to earn some $100,000 per appearance — or why bother showing up, ya know, right?

This is how you make money when you are (barely) famous for being famous; Paris Hilton wasn't the first to turn this into a business model, but she remains among the most notorious and highest-paid.

After Us Weekly supposedly tricked Lauren Conrad into bashing "friends" Audrina Patridge and Brody Jennfer, the Hills star found herself apologizing on her MySpace blog, blaming the tabloid for a bait-and-switch. Conrad, who is friends with the Us reporters she spoke to, was shocked to find EIC Janice Min went with a cover story that pieced together interview segments into a "How I Was Stabbed in the Back" article — so she went off on the tabloid.

Naturally, Min wasn't having it — she was left fuming after the press-needy Conrad slammed Us. Which means Conrad spent the weekend using Page Six to relay her apology to Min, who could easily kill the money train to Conrad if she stops buying paparazzi pics of her.

It's been a troubling week for Conrad, who then had to wake up this morning to see the New York Times crown foe Heidi Montag as a "feminist hero." Nevermind that even after all of this, millions of viewers watched her call friend Jenner "scum" on The Hills premiere. Or maybe we're in the middle of a Hills scripted segment?
