britney spears in las vegas with isaac cohen

Britney Spears and her new man, Isaac Cohen, have taken their hook-up to new heights: a Fantasy Tower suite at The Palms in Las Vegas.

Britney took Isaac, to 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 that spotted the two, who started dating in the past month. Hotel officials had no comment.

Call me crazy but don’t you think Isaac looks like K-Fed a bit?
