Spears and former manager Larry Rudolph
Britney Spears's post-breakup tour has taken her to Las Vegas – and she finally hit the town this weekend, winning big at the blackjack table and partying with Dancing with the Stars' Mario Lopez, sources tell PEOPLE.
After stops in New York and her Louisiana hometown of Kentwood, Spears, accompanied by her former manager Larry Rudolph, arrived in Nevada this week and kept a low profile before finally hitting the town on Friday.
Donning a disguise of a pink wig and big, dark sunglasses, Britney was
spotted in the Palms Casino Resort Friday night chatting it up with owner
George Maloof – this, after she and George went on a shopping trip to Caesars Palace's Forum Shops.
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 tells PEOPLE. "Her voice never sounded better. She's having fun. She's ready to kick a--."
Britney also did pretty well at the tables, gambling at The Mint, the Palms' high-limit lounge. There, Britney – wearing a short, black dress – caught a lucky streak, raking in $10,000 in winnings from blackjack.
She also was introduced to Mario Lopez at The Mint. The two, along with a small group, then headed up to Moon Nightclub and partied the night away.
