Spederline exes stretch out their 15 minutes

Britney Spears is hoping her first husband will think twice before publishing intimate details for their short-lived relationship. After announcing plans to write a tell-all book and revealing a few tidbits about Spears's breakup with KFed, Jason Alexander appears on an episode of the Dr. Ablow Show to air Monday with Federline's ex-girlfriend and mother of two of his children, Shar Jackson. Alexander said on the show that Spears had left him a voicemail that said, "Don't say anything you'd regret." Jackson, who had KFed over for Thanksgiving dinner, says, "[Federline]'s probably scared Britney might take his kids and go back to Louisiana and he might not see them."
