Britney’s $40,000 Night in Vegas

Britney Spears and Isaac Cohen have taken their hookup to new heights: a Fantasy Tower suite at The Palms in Las Vegas.

Sources tell PEOPLE the couple stayed in the tower's $40,000-a-night, two-story Hugh Hefner Sky Villa on Saturday, where a Jacuzzi pool, a glass elevator, an 8-ft. rotating bed and a full bar are among the amenities.

"They seem very happy together," says a source who spotted the two, who started dating in the past month. Hotel officials had no comment.

The trip was Spears's first appearance in Las Vegas since hosting a much-talked-about party at Pure nightclub on New Year's Eve – where, her rep told PEOPLE,she fell asleep.

It was a different scene Saturday night. Spears and model-actor Cohen, both 25, danced and smoked cigarettes at 8½, a gay club off the Strip before leaving after about an hour.

This is the second weekend in a row that the couple have been spotted together. On Jan. 6 they hung out on a powerboat off Marina del Rey, outside L.A., and the next night met up at the W Hotel's Whiskey Blue bar in Westwood.
