Britney Spears has forced radio syndication giant Clear Channel to remove three billboards in Tampa, Florida, which featured unflattering photographs of the pop star. According to a letter from Spears' attorney, the advertisement – which featured a photo of her shortly after she shaved her head, and labelled her a "total nut job" – was "offensive, unauthorised commercial exploitation". The ads were designed for radio station WFLZ FM's The Morning Show.
