Britney Spears has posted a warning on her official website urging fans not to fall for fake 'meet and greets' on internet auctions.
The star and her management have voiced concerns that devotees could be scammed out of their money by online fraudsters offering them the chance to meet their idol.
The singer insists fans should only enter legitimate competitions which have been set up in conjunction with Spears' ongoing Circus world tour - because online auctions could be fake.
A post on Spears' official website reads, "There have been recent sightings of internet auctions for fans to bid for a chance meet Britney. wants to warn fans about these fraudulent opportunities. These postings are fake.
"Fans would never be charged to meet Britney. The only meet and greets available for the Circus tour are through radio contests in select cities. Please be sure to listen to your local radio station to see if your city is eligible for a meet and greet. Do not bid for one online."
