And it’s also emerged that their relationship in fact kicked off six months ago.
The duo met properly last year on a commercial shoot.
Pitt, 55, and Theron, 43, shot an ad for watch brand Breitling last year with Adam Driver. The company released a sneak peek at the campaign back in September on their Facebook page.
“About six months ago, they did a shoot together. So they have spent time together,” a source dished to PEOPLE.
“But anything that may have happened beyond that remains to be seen.”
On Jan. 20, the U.K.’s Sun newspaper claimed that Pitt and Theron had struck up a romance over Christmas. Neither star has commented.
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.
Brad has kept a low profile in dating life since his split from Angelina Jolie in Sept. 2017.
He was linked to MIT professor Neri Oxman in mid 2018, though the high-profile architect later denied any romance between the two.
Charlize called off her engagement to Penn in 2015 and has since remained single.
