Britney Spears not allowed a phone

It is thought owning her own phone could land the 29-year-old singer in trouble, so those close to her have removed it to keep her "under control", the newspaper said.

The `Toxic` hitmaker, who has been under a legal conservatorship following her 2008 breakdown - which gives her father Jamie control over all her affairs - has had a number of conditions placed upon her in order to stop her from getting out of control.

"Britney`s inner-circle keep a close eye on her to ensure she keeps herself together. One of the rules is she gave up her cell phone. That helps them keep her under control," a source said.

The move comes after the star, who has sons - Sean Preston, five and Jayden James, four, with ex-husband Kevin Federline - was accused by her former bodyguard Fernando Flores of sending him nude pictures of herself from her phone, and then threatened to use them in a lawsuit against her.

In March, the pop superstar said that she didn`t have access to a mobile device.

"I don`t own a cell phone," Spears had said.

Meanwhile, her conservatorship is set to remain in place for the rest of the year.

"The conservatorship won`t be ending this year because everything is going well. Britney is on tour again, which she truly loves. This would be the worst time to make a change, while she is on the road, and is in unfamiliar surroundings.
