Britney Spears has been in Las Vegas since Friday.
She met up with 'Dancing with the Stars' Mario Lopez & partied the night away at Moon Nightclub, played a few rounds of something, most probably BlackJack & won around $10.000 after which she went on a shopping spree at Caesars Palace's Forum Shops.
Britney also did a bit of work, she went to Palms' recording studio with producer Lukasz Gottwald to mix tracks on her new album.

But, looks like the highlight of the week-end was when Britney met up with Paris Hilton! The two gals partied together at Tryst nightclub.
I wonder what those two talked about! ... I never imagined they would have something to discuss ... well, in all cases, they partied, danced & smoked together though!
