Los Angeles, Aug 20 - Hollywood actress Cameron Diaz and actor Jason Lewis are in a relationship. Speculation about them started after they were spotted on a sushi date on Venice Beach recently.

'Cameron and Jason were sitting in the corner of Shima (restaurant) totally wrapped up in one another. They couldn't stop touching each other,' aceshowbiz.com quoted a source as saying.

Cameron and the 'Sex and the City' actor have been friends for several years, but it wasn't until a few weeks ago that they began dating.

'They've always got along, but now realise just how much they have in common. Jason is exactly Cameron's type. She's attracted to athletic types and they're both passionate about the environment,' added the source.

Cameron has dated a string of men before she broke up with Paul Sculfor. Since splitting up from the model she's been romantically linked to the likes of Maroon 5's lead singer Adam Levine, actors Leonardo DiCaprio and Jude Law.
