Finding the right girl to play the role of girlfriend was an integral part of Spencer Pratt's plan for world domination. Heidi Montag won the job, and "The Hills" couple obnoxious-ed their way to marginal fame and fortune until the reality-TV show came to an end in 2010. The couple is now basically broke after blasting through $10 million of their MTV earnings. How did they manage that? "I would give my friends £15,000 for their birthday," Spencer told Britain's OK! magazine. "I would buy people cars. Every valet I met got a couple of hundred pounds tip. I would pay people £200 just to open doors for us." Heidi's probably so happy she let her hubby handle their expenses.
