Hollywood beauty Cameron Diaz has no intention of marrying boyfriend Justin Timberlake in the near future, because for her their union is already "spiritual". The Gangs of New York star, who recently admitted she is afraid of commitment, has been dating singer Timberlake for four-and-a-half years. She says, "I think that people find people and need people, but I just don't think it's absolutely necessary to walk down an aisle in a white dress and sign a piece of paper. "For me, it's spiritual. It's about whether two people have that commitment to one another."
