Simon Cowell was seen "making out" with Carmen Electra in a Hollywood restaurant at the weekend.

The music mogul and the former Baywatch actress enjoyed dinner at Cecconi's on Saturday and left together in the X Factor star's limousine and didn't seem to care who saw their flirty behavior.

"They were getting very cozy. They were holding hands and staring into each other's eyes - and then they started making out. They were with other friends at the restaurant but didn't seem to mind," a source told The Sun.

Carmen - who split from fiance Rob Patterson in May - is said to be enjoying Simon's company, though their romance isn't serious yet. "Carmen loves hanging out with Simon. They're having fun. She is getting back in the dating pool and Simon treats her very well. It's all very laid back at the moment but they are both enjoying themselves," the insider added.
