It looks like things are continuing to heat up between Cameron Diaz and Jen Aniston‘s ex boy-toy, Paul Sculfor.

One week after their romantic dinner at Santa Monica’s Il Ristorante di Giorgio Baldi, the pretty pair was spotted looking head over heels for each other at the Chateau Marmont in Hollywood on June 8.

"Cam and Paul were sitting on the patio, leaning in toward each other," one eyewitness tells OK!. "Her body language looked like she was really comfortable with him. She looked genuinely like a girl falling in love."

Though Cameron, 35, often frequents the Chateau with her female friends, this is the first time she’s been to the hot spot with British model Paul, 37. "She wasn’t really hiding him," says the witness.

While the relationship seems to be getting serious, an insider insists to OK! that Cameron hasn’t completely gotten over former flame Justin Timberlake: "She has been calling him constantly for support after the passing of her father, and it must be driving Jessica Biel nuts."
