Spencer Pratt and Heidi Montag.

A nightmarish example of the current arc of celebrity careers, Heidi Montag first appeared in the limelight as one of the vapidly attractive cast members of MTV's hit reality show "The Hills" in 2006. She and a crew of affectless Southern Californians drifted into a kind of achievement-free stardom typical of the era. What were these people famous for? No one really knew.

But Montag, after hooking up with fellow cast member Spencer Pratt, became well-known for all the wrong reasons. With Pratt egging her on, she launched an ill-advised pop music career that cost her nearly two million dollars. The resulting self-released album famously sold fewer than a thousand copies in its first week of release.

An attempt at a fashion line, Heidiwood, was another expensive failure, dropped by partners Anchor Blue Retail Group after less than a year of operation.
