Britney Spears is back to Las Vegas & she's not alone. She took along model Isaac Cohen for a couple of days of fun in Sin City!
Now, where would Britney stay the night after partying in clubs like the gay nightclub 8 1/2?
She & Cohen ,who are both 25, spent the night together in the Hugh Hefner suite of a Las Vegas hotel on Saturday night. This is not any ordinary suite ... This is a $40,000-a-night, two-story Hugh Hefner Sky Villa, which has an 8ft rotating bed, a Jacuzzi, full bar & a glass elevator. Now what do ya think of that?!

It seems Britney's relationship with Cohen is evolving into something more than just hanging out ... She's been seen with him nearly every day for the past 10 days!
I hope she knows what she's doing ... She's prawn to making mistakes & they are usually serious mistakes ... Like a crazy chapel wedding a couple of years back & then marrying that no-good K-Fed!
