Timberlake, Diaz still together?

London: Pop singer Justin Timberlake finds working with ex-girlfriend Cameron Diaz exciting during the shooting of their upcoming flick "Bad Teacher".

Timberlake said they have found it hard to become friends after their split but now they are completely enjoying the togetherness. "We were happy to have this movie together because we share a sense of humour, always have, always will. We`re great friends, and we had a great experience together, and now were having a great experience together in a completely different way," femalefirst.co.uk quoted the 30-year-old as saying. Timberlake broke up with girlfriend, Jessica Biel, last month and although Cameron is still reportedly in a relationship with baseball star, Alex Rodreiguez, there have recently been rumours of their split.
