Once upon a time ago, Heidi Montag was a sweet girl from Colorado who just so happened to befriend an MTV reality star during orientation at a San Francisco art school. Then, like so many before her, she moved to (West) Hollywood, was blinded by the lights of the reality show cameras that followed her every move, and become fixated on fame, beauty, and perfection. She got involved with Spencer Pratt, and, together, the two attempted to monopolize The Hills with their fake relationship and friendship drama. Montag, along with Pratt, even spread a rumor about her now-former BFF Lauren Conrad, claiming that there was a sex tape floating around featuring Lauren and Laguna Beach/The Hills star Jason Wahler.
There’s a saying that all press is good press, but that doesn’t apply in the case of Montag, whose face has, by now, appeared on the cover of virtually every tabloid out. That's what happens when you do things like have ten plastic surgery procedures done in one day. We wish her the best living with Pratt at his parents’ home in Santa Barbara.
