Britney's Conservator -- Tap This!

Jamie Spears was drinking at a bar this weekend. But contrary to several reports, we're told it was NOT alcohol.

Spears was at Big Dean's "Muscle In" Cafe in Santa Monica Friday night. He was bellied up at the bar, drinking two or three glasses of something. We're told it was O'Doul's, not beer.

If Jamie had been drinking beer it would be a big deal -- he's a recovering alcoholic and guzzling suds could jeopardize his conservatorship over Britney.

We're told he drank his O'Doul's and walked out with a cheeseburger and chili fries.

There were reports the liquid came from a tap. We checked and turns out O'Doul's does come in keg form. We did not know that.
