Britney Spears and her sons touched down in Las Vegas on Saturday ahead of her two weekend performances in the city to finish up her US tour. Miley Cyrus and Lance Bass both came out to see her Circus and Lance was even treated to a lapdance during last night's show. Britney now has a month off before she heads to Australia for the first time. Britney's 50/50 custody agreement with Kevin Federline has been extended, so she'll have Sean Preston and Jayden James half the time until the arrangement is reevaluated at the end of the year. In Vegas she stopped by a candy store with SP, JJ, and Jason Trawick, so perhaps their romance isn't totally over after all. She also set a world record with her fifth number one album — congrats to Britney!
