Britney Spears

Britney Spears is reportedly furious over claims that she enjoys lesbian sex and pornography.

The singer has vehemently denied allegations that she has for years partaken in threesomes and keeps pornographic material in her house.

The accusations came from rap artist Omar 'Iceman' Sharif - a friend of Spears' estranged husband Kevin Federline.

He told In Touch magazine, "Britney was into threesomes and girls. There was tons of porn in the house - but it was mostly Britney's."

The magazine also quoted a number of "insiders" testifying to the claims. One said: "Sometimes it was three girls and sometimes it was more like six."

A spokeswoman for Spears has denied the allegations.
