Jason Alexander is in jail. No, not jail for Seinfeld Jason Alexander but Britney Spears’ Jason Alexander. Britney’s first husband of two days is in jail for violation of his probation .. in Los Angeles.

Two days? Actually 55 hours.

But what’s the southern ex husband doing in Los Angeles? No clue.

While Alexander was married to Spears a whopping 55 hours, he will have to stay in jail long than that – 10 days – for probation violation of a 2006 DUI arrest.

Spears was married to him January 3, 2004 for 55 hours and thereafter had an annulment …. on grounds reportedly she didn’t know what she was doing.

Didn’t know what she was doing? And from there, she married Kevin Federline.
