Beautiful actress Cameron Diaz denied rumors about her and boyfriend Justin Timberlake splitting up, arguing whatever happens between them is nobody's business and tabloids shouldn't publish lies about their relationship.

Diaz, 33, who began dating pop singer Justin Timberlake in early 2003, declared they trust each other and know the truth about them and their relationship, claiming magazines write rumors about them to increase their sales.

She muses: "It's funny. We get these things every few days where one magazine is saying we're breaking up and the other magazine is saying that we're moving in together.

The another magazine says we're getting married next weekend.

But we know what the truth is. It doesn't hurt us," Cameron added.
