Britney Spears sued over security bill

Britney Spears is facing a legal battle over allegations she failed to settle a bill for her security detail.

The Toxic singer, who is under the conservatorship of her father, is accused of ending her contract with Advanced Security Concepts Corporation in 2010 without paying more than $140,000 in fees.

Company bosses have filed suit against Spears' estate demanding the money for the remainder of a one-year contract which was terminated early, according to TMZ.com.
