Britney Spears keeps it busy in Sin City.

The "Scream & Shout" singer spent last weekend in Las Vegas but she wouldn't have come at all if her much-discussed Vegas residency was not a "done deal," the Las Vegas Sun reported.

With new boyfriend David Lucado in tow, Spears flew to Vegas Friday and checked into Caesars Palace, the Sun reported. She attended a charity Cirque du Soleil performance, sneaking in just as the curtain went up and leaving just before the show ended. Spears tweeted a photo of herself, Lucado and her manager, Larry Rudolph, smiling in their seats together.

Spears' management and production team met with executives at Caesars Entertainment Saturday, which owns Planet Hollywood, and then checked out the PH Live theater, where Brit will have her residency. Spears, Lucado and her entourage then lunched at the Meatball Spot restaurant, owned by Top Chef Seattle contestant Carla Pellegrino. The couple chowed down on meatball sliders with mozzarella cheese, macaroni and cheese and a bananas foster ice cream sandwich. An onlooker told People magazine that they "seemed happy, sitting across from each other and chatting for most of the meal."

Saturday night, Spears took in Shania Twain's show at the Colosseum at Caesars Palace and reportedly checked out the PH Live theater herself on Sunday before returning to L.A.

Spears' residency, which will consist of 40 weekend shows over two years, won't start until next spring or this perhaps fall, at the earliest, the Las Vegas Sun reported.

"Everything should be announced officially in a couple of weeks," a source told the paper. "Then Britney will be back, and there will be a real celebration."
