Celebrity News:

A sex tape 'starring' Britney Spears has been exposed as a hoax.

A 30-minute video of the troubled star was reported to have been leaked on the internet.

The raunchy footage was said to show a bald Britney performing sex acts on two women and a man, while consuming alcohol, cocaine and marijuana.

But it was all the work of internet jokers, who added material to a genuine news story about the 26-year-old singer.

Plenty of rumours have surfaced before about secret sex tapes starring Britney, but they've all turned out to be fakes.
