Simon Cowell is rumoured to be dating Carmen Electra.

The stars were spotted enjoying an intimate meal at Italian restaurant Cecconi's in West Hollywood on Sunday evening. Reports state that the 53-year-old music mogul and former Playboy playmate Carmen couldn't keep their hands off each other.

"They were really into each other," a fellow diner told In Touch. "At one point, they were talking real close, and he leaned in and kissed her. They started making out!"

The duo first sparked rumours they were interested in each other when Simon signed up Carmen to appear as a guest judge on Britain's Got Talent in February. At the time of her stint on the show Carmen was engaged to rocker Rob Patterson, but the pair split in May.

Simon and Carmen were reportedly flirting with each other during auditions for the variety show contest.

According to British newspaper the Daily Mail, the other judges on the panel were frustrated that they were paying more attention to each other than the acts they were judging.

When asked at the time why he chose Carmen, Simon flattered the 40-year-old's model looks.

"She has the best set of teeth I have ever seen," Simon subtly quipped.
