Britney’s first ex-husband, Jason Alexander, whom you may remember from his 15 minutes of fame when he was married to young Brit for about 2.8 seconds after a quickie Vegas ceremony, is now spilling his guts all over the place. That’s right, someone’s got a tell-all book to promote. From TMZ:

Britney’s 55-hour ex-husband Jason Alexander appeared with Fed’s baby mama Shar Jackson on “The Dr. Ablow Show,” where Alexander revealed that Britney contacted him by leaving a voicemail saying, “Don’t say anything you’d regret.”

Between the bullshit going on with Michael Richards and this particular Jason Alexander, it’s got to suck (by association) to be this guy at the moment.
