"It's a guys weekend," a source told the magazine.
K-Fed enjoyed a little poolside relaxation, dinner at Nobu and nightclubbing, according to the magazine.
A recent family incident didn't keep Federline from enjoying Sin City — his younger brother Cameron was busted April 3 for providing liquor to minors in Pendleton, Ore., CBS Radio News reported Thursday.
The 20-year-old was being held in the Umatilla County jail in Pendleton charged with providing liquor to minors and of being a minor with alcohol and was scheduled to be released on Saturday.
Spears and Federline reached a confidential divorce settlement March 29 after a five-hour meeting with their attorneys present, the Associated Press reported.
