Trust me when I say it kills me to write this story.  Because it means probably sooner than later Adam Levine will be officially off the market.  The Maroon 5 front man is set to wed Victoria's Secret model Behati Prinsloo, and he recently had his last hoorah in Las Vegas.
Levine, 35, and his crew of guys, headed to Sin City following The Voice finale.

The Destination: The group of about 50 partied in the Palms Casino Resort's Hardwood Suite, a 10,000 square foot room boasting an indoor basketball court, professional locker room, dance floor and 24-hour butler service.

The Dinner: The party moved to the famous N9NE Steakhouse Wednesday night for a lavish dinner.

"Everyone in the restaurant recognized him," a source close to the singer said. "He was saying hello and chatting with everybody in the restaurant."

The Food: The group sampled chilled seafood platters, steaks and salads. They were also seen drinking shots of high-end 1942 tequila, People.com reports.

The Entertainment: Later, Levine was spotted gambling in the Mint, the Palms' high-limit area.

With Maroon 5's new album V due in September, its a safe bet that Adam will be marrying Behati sometime this summer before his band gets going with their upcoming tour.
