OK! Magazine reports that Cameron Diaz's romance with Paul Sculfor is really heating up. A week after their dinner date at Giorgio Baldi, the twosome hit up the Chateau Marmont this weekend and, according to an eyewitness, Cam "looked genuinely like a girl falling in love."

But wasn't she just hanging out at the Chateau with Gerard Butler? And more recently, she's been linked to P. Diddy (or whatever his name is)!

Damn, Cam - slow down!
