Despite being confirmed by representatives of Heidi Pratt, sources close to the stars of "The Hills," Heidi and Spencer Pratt, say the recent reports of their break up were a joke, according to Us Magazine.

One inside source told the publication that… "Heidi and Spencer are laughing over it and having a blast." In addition, Holly, Heidi’s sister, sent out a tweet declaring that the duo were "liars."

The goal of leaking a story about their break up was to generate publicity as "The Hills" comes to a close, according to the sources. "This breakup is the latest part of Spencer’s master plan," says another source.
