New Couple Alert

Britney Spears and Isaac Cohen are officially a couple. So she dumped Kevin Federline for someone who looks like him, just not as bad. Hmm, ok?

SHe continued to neglect her kids by taking off out of town and going to Vegas with her new boyfriend. They stayed in 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.

What about her two kids? She hasn't stayed home hardly one night since she dumped K-Fed. I have seen a few photos of her out with Sean Preston during daylight hours, but it has just occured to me that no one has seen her second child. Where is he? Hmm....
