Three staff members of pop star Britney Spears have been fired by her father for suspected drug use on her comeback tour.
The concerned dad and the pop star's manager are being extra strict to keep drugs away from the tour, mirror.co.uk reports.
A source said: "Because of Britney's past personal problems, she now requires more insurance for her Circus tour than before. It's a very rigorous process protecting all of those assets. Backstage her dad is beyond strict and rightfully so. He only wants the best for Britney."
