Brad Pitt and Charlize Theron have reportedly been dating for about six months, after meeting on a commercial shoot, sources tell People.

Pitt, 55, and Theron, 43, shot an ad for the watch brand Breitling last year. Adam Driver also starred. Rumors of their reported romance surfaced over the weekend via U.K.’s The Sun. So far, no word from the stars or their reps.

The rumored romance is a big deal, not just because they are two of the biggest stars on the planet, but also because Theron and Pitt’s estranged ex Angelina Jolie have long been foes, reportedly having a rivalry over juicy film roles. 

Pitt has kept a low profile since his split from Jolie in September 17th.
