Cameron Diaz is baffled by the fuss surrounding her upcoming movie with ex-boyfriend Justin Timberlake, insisting she can't understand the "mentality" of people who don't get on with their former lovers.
The Charlie's Angels beauty dated the pop star-turned-actor from 2003 to 2006, and they remained pals after breaking up.
After it was announced they would star opposite each other in new comedy Bad Teacher, gossip went in to a spin over how the former couple could work together in such close proximity.
But Diaz insists she hates living in the past and has no issues working with her ex-partner - because they only want "happiness" for one another and know how to have fun on screen.
She tells Britain's Elle magazine, "Life is long. Why would you ever live in the past when you can live in the present, and allow the future to be bright and happy and exciting? There's no reason.
"I think people's mentality is, 'It didn't work out!' But, like, what didn't work out? What's supposed to happen? I think a lot of people are married to people that they're not romantic with any more. I just didn't ever marry anybody that I then had to get divorced from. We break up. We move on.
"All I want for him is his happiness. And all he wants is my happiness. His isn't reliant on me, and mine isn't on him. It was at one point; we had that moment, but now... let's make a movie. Let's go have some fun. We're good at being funny together. We know how to do that. That's easy."
