It's a good thing she's gotten so much publicity for that book (ahem) because according to Page Six, Bonnie Fuller may soon be out of a job.

Last Tuesday AMI head David Pecker got rid of Celebrity Living, car-buff mag MPH and the Spanish- language edition of fitness magazine Shape - but the cost-cutting isn't over. We hear there is "going to be major cost-cutting at Star - every nickel will be watched," said our spy.

Word is that Star and the National Enquirer may be put on the block soon. Either way, editorial director Bonnie Fuller - despite protestations - may be out of a job anyway. Spies said Pecker has no intention of renewing Fuller's contract, which is up in two months.

We're pretty sure the nickles are already watched pretty closely — especially when it comes to feeding the staff and tipping at restaurants. But if Bonnie's contract is not renewed, where will she go? Who will Star hire?

Word better come soon. Without Star, Us Weekly becomes the dominate party. And with only Life & Style and In Touch running up against it, the mag could rule the tabloid system, meaning Jann Wenner would rule the world.

Bonnie has to be resigned, she just has to. If only to protect the world from its worst nightmare (besides Tom Cruise and Katie Holmes' baby) coming true.
