Watch them prattle?

Reality TV personalities Heidi and Spencer Pratt say they want to branch out from MTV’s “The Hills” and star in their own reality show.

In an interview to promote their new book, “How to be Famous: Our Guide to Looking the Part, Playing the Press, and Becoming a Tabloid Fixture,” the couple said they’re shopping the idea around to various networks.

While “The Hills” only focuses on a small part of their lives, they said, their own show would reveal everything that happens to them. They’d even be willing to include live segments.

“You don’t get to see our everyday lives and what we do,” Heidi Pratt said.

But the Pratts also said they don’t plan to leave “The Hills.”

Last summer, the newlyweds appeared on NBC’s “I’m a Celebrity … Get Me Out of Here!”
