Sex and the City's Kim Cattrall has often stripped off for her role as the racy Samantha - but in new scenes for the highly-anticipated big screen version she appears to have revealed rather more than she would have liked.

The actress' massive bikini bottoms failed to hide the dimpled truth, as her cellulite was plainly on show while she filmed scenes on the Malibu beach.

As the blonde star strode along the beach, gold stilettos in hand, despite retaining a still enviable figure, her thighs showed the tell-tale signs of the dreaded skin condition which defeats many women.

Kim wore a 50s style black halternecked bikini to film scenes on the deserted beach. And the large tummy-covering pants had more than a hint of the Bridget Jones' about them.

But unlike Bridget's control pants, unfortunately for Kim, they did little to enhance the Sex and the City star's still svelte figure.

But, dreaded cellulite aside, the 51-year-old actress is clearly still in pretty fine fettle.

And fans of the film are expecting plenty of the raunchy scenes that are now associated with her outrageous character, PR woman Samantha.

The film has been dogged by rumours of on-set rows, mainly involving Cattrall and actress Sarah Jessica-Parker.

And in new reports from the US, an insider is set to blow the lid with a behind the scenes memoir.

According to the New York Post, Clifford Streit, the former manager of author Candace Bushnell, is touting a book proposal of the series' early days titled "Unbecoming Stanford."

The book is named after Stanford Blatch, the character who was Carrie Bradshaw's flamboyant gay best friend played by Willie Garson, as it was intended as a caricature of Streit.

Recently, Bushnell and Streit amicably settled a financial dispute over payment from the show.

The book suggests tensions on set began because Kim Cattrall was "a natural comedienne, and a scene-stealer in the best possible sense - the camera went right to her."

Streit also claims two of the show's on-screen lovers had an affair off-screen too.

And that executive producer Darren Star passed on Ashton Kutcher for the show because, he privately confided after a dinner meeting: "I don't see this kid going anywhere."
