Cameron Diaz, Sean Combs working on movie project

New York, Nov 15 : Actress Cameron Diaz and singer Sean Combs aren't dating rather they are working together on a film project, says her representative.

Rumours of their budding romance started after they were spotted dining together a number of times in recent weeks. However, Diaz's spokesperson has set the record straight.

"(They) are longtime friends and have been seen together recently because they are developing a film project. They had lunch... with a producer who is also involved in the project. (They) are not romantically involved," nypost.com quoted Diaz's representative as saying.

Diaz split from baseball star Alex Rodriguez in September, while Combs has been linked to singer Cassie.
