The romance between Cameron Diaz and Diddy must be casual or over, because she was seen out on a dinner date with Paul Sculfor, the hot British male model who first gained tabloid fame by stepping out with Jennifer Aniston last June. The gossip mill claimed at the time that Sculfor was just using Aniston for her fame and money, and if that was true he may be up to his old tricks again. US Weekly says he had Diaz laughing a lot over their romantic dinner and that she looked “really flirty.” Diaz used to date jabbering John Mayer, who is now dating Sculfor’s ex, Jennifer Aniston, which essentially means they’ve switched partners:

[On Saturday] Diaz went on a dinner date with Aniston’s model ex Paul Sculfor.

The two hit up Il Ristorante di Giorgio Baldi in Santa Monica, California, Sunday.

“Cameron was laughing at everything he said — she didn’t stop smiling,” an onlooker told Usmagazine.com. “She was really flirty and had three or four of her buttons undone.”

The story we reported on earlier today about Diaz and Diddy at Prince’s party happened last month, and the news is just getting out now. I thought when I first heard this that she might be dating two guys at once, not that there’s anything wrong with that. If you’re famous and dating there must be a way to keep it relatively quiet if you don’t hit the parties and hot spots. You’ve probably got to pick out of the way places, but even then other guests and staff still might blab.

Cameron talked about being single and dating in her much-quoted interview in In Style, in which she exclaimed “I love sex!” She said “People think if you’re single, you are incomplete. No. The thing is, I don’t want to be in a relationship that makes me incomplete.” She also said she’s dating and that it’s not a big deal “I’m a woman. Of course I’m dating. And is that so surprising? Oh my god, she’s dating!”
