Hollywood actress Cameron Diaz confesses she is a "commitment-phobe" and therefore has no plans to marry her boyfriend, singer Justin Timberlake.

Appearing on "The Ellen DeGeneres Show," the 34-year-old actress dismissed wedding rumors when she was asked whether Timberlake's comments on the program in September held any truth, People magazine reported.

"You know the answer to that, Ellen," Diaz said. "I'm a commitment-phobe. Don't want to do it."

The actress, who will next appear on screen in "The Holiday," also defended her hobby of aggressively pursuing bouquets at weddings despite her negative view of walking down the aisle.

"It's like a sport to me," she said. "I don't care. I don't want to get married. I just want to catch the bouquet, because I have a collection of bouquets. I don't have them still, but they're kind of in my ego catalog: 12 bouquets."

People said Diaz had previously made comments that she also has no plans to have children or even own a dog due to her problem with commitment.
