Spencer Pratt and Heidi Montag won’t let anything get in the way of their quest for fame — not even reality. They’ve been pushing their split by trying to sell a made-up story that Heidi may be cheating with Spencer’s close pal, Marine-turned-bodyguard Cougar Zank.

A source told us, “Heidi and Spencer are try ing to play out a fake reality show in the press and get paid along the way. They’ve been approaching magazines and Web sites to buy the fake story of Zank having an affair with Heidi. They’ve been asking for $100,000. But no one is interested as they don’t sell magazines.” A rep for Pratt and Montag didn’t get back to us.
