Only one week into her saucy-circus themed world tour, Britney Spears' team have decided to let three of her dancers go for reportedly dabbling in drugs. 

The pop princess - whose shows include eye-popping special effects and dazzling dance routines - is down three dancers after daddy Spears, Jamie and manager Larry Rudolph fired them for suspected drug use.

An insider tells the Daily Mirror: “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."

The source adds, “He’s protecting Britney’s comeback with every ounce of his being.”

Meanwhile Britney doesn't seem to have a care in the world - the pops sensation was spotted lapping up the sun in Miami with her boys Sean Preston and Jayden James.
