LOS ANGELES: Britney Spears has won her court battle to extend her ‘Circus Tour’ across Europe - the singer has been granted permission to play live shows in cities including Paris, Moscow and Berlin.

The Toxic hitmaker, who remains under the conservatorship of her father Jamie, went to court in Los Angeles earlier in April to seek permission to take her shows beyond North America, Canada and Britain.

It was feared the judge overseeing the case would deny the star the right to tour mainland Europe, amid worries over the sinking value of the dollar and the weak U.S. economy.

But court officials have ruled in Spears' favour - granting her permission to extend her shows through the summer.

Spears kicked off her U.S. tour in her home state of Louisiana on 3 March and will fly to Britain for a run at London's O2 Arena in June. She will then take the tour to Ireland, France, Belgium, Denmark, Sweden, Russia and Poland before heading to Berlin, Germany to wrap up the European leg on 26 July.

Spears is reportedly still waiting for a decision on whether she will be able to tour Australia later this year.
