Cameron Diaz may be getting sexy back with her partner of four years, Justin Timberlake, but the two are unlikely to ever walk down the aisle. It appears that the actress, who stars in the upcoming The Holiday with Kate Winslet, Jude Law, and Jack Black, is afraid of commitment to the point that she’ll never tie the knot.

The star of Charlie’s Angels, There’s Something About Mary, and My Best Friend’s Wedding appeared on The Ellen DeGeneres Show last night and said, "You know the answer to the question of getting married. I’m a commitment-phobe. I don’t want to do it. Anyway, we’re kind of like married."

Cameron Diaz may be "kind of like" married to Justin Timberlake, but she also seems pretty afraid of any kind of commitment, even revealing recently that she doesn’t even want the responsibility of a pet dog, according to Monsters and Critics.

She did tell Ellen however that she does like to catch the wedding bouquet - "I don’t fight, it’s not about fighting. It’s about being in the right position. The right place at the right time. Ever heard of that, ladies? It’s like a sport to me. 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 catalogue - 12 bouquets."

Justin Timberlake got the same questions as Cameron when he appeared on the show in September - when you’ve been together four years, questions like that come up - and when Ellen DeGeneres joked about picking out a bridesmaid dress, Timberlake responded with "You know what? Go ahead and reserve one. The only thing is you’ll have to stay the same size for the next 15 years."

In other Ms. Diaz news, WENN revealed that the star’s new do, a brunette look to replace her typical blonde locks, is getting the actress more respect. The news service quoted Cameron Diaz as saying, "People react differently definitely... I guess it’s just because I feel more grounded with it. It’s interesting, you get the different expressions from people. (I’m approached by) different guys. The darker guys tend to come at you, as well. A guy that’s a little bit more introspective that’s looking for a more introspective girl. It’s amazing the thing we have in our minds about blondes and brunettes, but it’s kind of fun to play with it both, because people still see me as a blonde so they kind of react to me in that way as well. It’s just a trick. I’m just tricking ’em for a bit."

In movie news, Cameron Diaz’s turn in The Holiday opens December 8th and the actress just finished voice work on Shrek the Third hitting next summer, while Justin Timberlake’s work in Alpha Dog will finally land in theaters in January with Southland Tales and Black Snake Moan to come later in the year.
