Britney Spears is going “Down Under” next month, and the pop star has asked her entourage to undergo regular drug and alcohol tests before they hit the continent.

The 27-year-old hitmaker will perform for the first time in Sydney, Melbourne, Brisbane, Adelaide, and Perth in November and has laid down strict disciplines for her employees if they want to be on the tour, tattles tell The Herald Sun.

“Britney’s rule is clear zero tolerance. No drink. No drugs. If you do not comply, you do not tour with Britney,” says a spy.
