Britney Spears has reportedly spent $700,000 renovating her home.

The '3' singer spent the huge amount on various projects on her lavish Californian property, including on decorating, new furniture and electronic equipment.

A source said: "Britney remodelled her entire home. She loves spending money."

According to the insider, as well as a reported $200,000 spent on artwork, Britney splashed out $150,000 on electronics, purchased a new $100,000 bathroom, paid $100,000 for Venetian plaster walls and bought $150,000 of new furniture.

Meanwhile, Britney's lawyers have moved to make sure confidential information about the pop star and her children, Sean Preston, four, and three-year-old Jayden James, are legally sealed amid fears her private medical information could be leaked.

Lawyers Geraldine Wyle and Jeryll Cohen said in legal documentation: "A Google search for Ms. Spears' name yields 54,300,000 hits.

"Photographs and personal information, particular information of a highly confidential nature (such as personal medical information of Ms. Spears and her children), can potentially reap thousands if not millions of dollars.

"The possibility of such enormous profits presents a substantial risk that Ms. Spears' most confidential medical and personal information will be disclosed."
