London, July 21 - Actress Cameron Diaz seems to be involved in a love triangle with her former co-stars - Leonardo DiCaprio and Jude Law.

Thesun.co.uk reports that over the past week DiCaprio and Law have been on several dates with Diaz.

'DiCaprio is back on the pull after he split from his long term girlfriend Bar Raefeli. Diaz has been showing a lot of interest while he is in London filming. She was back at his rented apartment in Knightsbridge, west London, a couple of times last week after a series of secret dates. They were joking with friends that they played

chess together,' said a source.

'Law and Diaz have been good friends since they filmed 'The Holiday' together a few years ago. Now they are both single, things are a bit different between them. Law has been flirting with her and she has been playing along,' added the source.

Diaz more recently split from British model Paul Sculfor and was also involved in a long term relationship with pop star Justin Timberlake.
