A source tells PEOPLE that the two aren’t romantically involved after they met shooting an ad for watch company Breitling along with Adam Driver last year.
Pitt and Theron “did a shoot together six months ago. They have not been out together recently, and were never dating. Reports of them being involved romantically are false,” the source says.
The company released a sneak peek at the campaign back in September on their Facebook page and a video featuring all three stars during the shoot.
On Jan. 20, the U.K.’s Sun newspaper claimed that Pitt, 55, and Theron, 43, had struck up a romance over Christmas.
As for the Sun‘s claim that Theron’s ex, Sean Penn, played any role in introducing them: “That couldn’t be more false. Not in the slightest,” the source adds.
