A massive set, an illuminated onesie and hair extensions (lots of them) means only one thing: Britney’s back. More than 1,000 fans were treated to a surprise mini-concert Friday night at Rain Nightclub inside the Palms, featuring longtime pop princess Britney Spears.

Security was extremely tight due to MTV film crews (the channel was filming a TV special, set to air next week). Press was denied access.

Cover charge for Rain was set at $60 for the night, Spears’ first performance since her Circus Tour.

But the endless lines and jam-packed nightclub suggest fans were willing to pay the price.

DJ Pauly D of MTV’s Jersey Shore warmed up the crowd before the show, gaining nearly as much attention as Spears.

Spears showed no signs of being rusty. She was timely, appearing just a few minutes after the scheduled midnight set time.

Physically, each of her costumes left little to the imagination. The pop diva flawlessly pranced around the stage with her equally toned backup dancers. During the debut of the Will.I.Am-produced track “Beat Fat Bass,” Spears climbed speaker boxes and scaffolding.

“It’s so good to be back,” she told fans with a huge smile, delving into her new hits “Hold it Against Me” and “Till the World Ends.”

The sound was pop perfection, but there was little, if any, live singing, at least not from Spears herself — something the fans clearly accept.

“She’s totally lip-syncing,” one girl whispered to a friend.

“Duh,” her friend replied.

Spears’ latest album, Femme Fatale, is set to release Tuesday.
