Sexy Scotsman Gerard Butler and Jessica Simpson, along with a few friends, broke bread at Soho House in New York Tuesday.
An onlooker close to the celebrity diners told the NY Post: "They were at a table with friends, but Jessica and Gerard, who sat next to each other, seemed to only be interested in each other and chatted for hours.
Also at the dinner was Simpson's confidante and hairdresser, Ken Paves.
"They were laughing and flirting and eventually left together, along with Ken," the source told the paper.
Butler has been romantically connected to A-list actress Jennifer Aniston, while Simpson's relationship with Dallas Cowboys QB Tony Romo ended this summer.
