Britney's Wild Vegas Weekend!

Brit looks like she's having a great time, huh?!

Is it just me or does the poor girl look zoned out on a bunch of meds?

What can you do? ... Poor Britney. She can't even have fun in Vegas -- but of course she's surrounded by people hired by her dad, NOT chosen by her.

She went to see the Cirque du Soleil Beatles' Love show last night at the Mirage after hanging at the pool yesterday.

She looked like she was having a better time sunbathing - CLICK HERE to see that gallery.
