Liz Hurley has hit back at claims from the US that she had 'a year-long affair' with Bill Clinton, calling them 'ludicrously silly stories'.

Reports first broke earlier today from US site RadarOnline.com, which claims to have a recording of Hurley's ex Tom Sizemore telling unidentified people that Hurley and Clinton had an affair while he was in office.

The alleged affair happened in 1998 according to the report, while Clinton was still President. However, Hurley was quick to jump on the internet and tell everyone on Twitter how she feels about the whole thing, and how she is lawyering up.

Bill Clinton has not yet responded to claims, according to Sky News.
