DUI, Annulment Does a Body Good

Britney's first husband is looking like he dropped some serious LBs -- too bad it took his mug shot for us to notice it.

Jason Alexander checked into jail to serve 10 days for a prior DUI conviction.

For all the crazy Britney photos we've seen over the past few years, at least she doesn't have a mug shot out there.
