Britney Spears and Mario Lopez Roll the Celebrity Dice in Las Vegas

What happens in Vegas stays in Vegas.

Unless you're a famous singer that recently divorced your waste of wife-beater-wearing space husband and a curly-haired hot dancer that should have been crowned the brightest dancing star on the planet.

Indeed, the Britney Spears post-breakup tour took Sean Preston's mom to Las Vegas this weekend. Once there, the former Mrs. K-Fed won big at the blackjack table and may have landed an even more impressive pot:

Mario Lopez.

She was introduced to the Dancing with the Stars runner-up at casino, The Mint. The two, along with a small group, then headed up to Moon Nightclub and partied the night away.

Before possibly taking the man that played A.C. Slater to the wrestling mat of her hotel room (if you know wat we mean!), Britney arrived in Nevada on Friday.

She donned the disguise of a pink wig and big, dark sunglasses, but was spotted in the Palms Casino Resort Friday night; probably due to the fact that Britney Spears boobs are never confused with anyone else's cleavage.

Also on Friday, Spears went into the Palms' recording studio with producer Lukasz Gottwald to mix tracks on her new album.

"She looks and sounds great," a source told People magazine. "Her voice never sounded better. She's having fun. She's ready to kick a--."

Britney also did pretty well at the tables, reportedly winning $10,000 playing blackjack.

That's more cash than Kevin Federline album sales will bring in over the next six years.

Meanwhile, two famous folks were absent from the trip. There were no Jayden James Federline sightings, spurring talk that Spears is trying to keep the child away from gambling.

Karina Smirnoff, Lopez's possible girlfriend, was also nowhere to be seen. We hope she's okay.
