AceShowbiz - Britney Spears has hit back at false tabloid reports which sparked speculation she is deliberately hurting herself - her reps have published the stories on her official website with a warning banner. America's The National Enquirer and The Globe in March alleged the "Toxic" superstar had been self-harming after she was spotted sporting a nasty-looking bruise on her arm.

The National Enquirer report even claimed the star had plunged down a flight of stairs, and was only saved from real harm after a bodyguard grabbed her before she hit the floor. But the star has reached out to fans to convince them the reports are false by ordering the manager of her website to strike through the tabloid pages with a "Bulls**t Alert".

The pages of the magazines appear on her official site, with the alert, as well as a message from the website's boss. The post reads, "The Enquirer and The Globe are printing more bulls#!t! Check out these ridiculous stories - Adam, Manager."
