    "I lost my voice at the craps tables and I lost all my money," Federline rambled on at one point encouraging everyone to have a good time as he got his hands on a microphone, before a pal dragged him away, as media reported.

    Federline left the club a little before 2 a.m. and returned to his Caesars Palace suite. He is expected to leave Las Vegas Saturday and head back to Los Angeles,

    During his celebration, Federline's sons with Britney, Preston and Jayden, stayed in the care of their nanny and a bodyguard.

    Spears has spiraled downwards since her divorce last year from Federline. She has lost custody and visitation rights to their two sons for her bizarre antics.

    She also has to pay Federline 15,000 dollars per month in child support and 20,000 dollars in spousal support.
