Brad Pitt and Sienna Miller were rumored to be dating after the actor's divorce from Angelina Jolie, and last year, one report even claimed that they were taking their relationship to the next level. However, these claims have been proven to be false.

The Australian edition of OK! magazine released a story last year on New Year's Day that Pitt and Miller were "getting serious" after dating "casually" for months. Prior to this, rumors were rampant that the two actors were in a relationship, but these had died down around August 2017. It wasn't until OK! released this false report in January 2018 that their so-called "dating life" was once again put in the spotlight.

“Brad thinks she’s gorgeous," an unnamed source claimed to the mag. "She thinks he’s gorgeous. They’re definitely into each other. ... Pals say they wouldn’t be surprised if this ends in wedding bells.”

Gossip Cop recently looked back at this story and pointed out that, one year later, there doesn't seem to be any sign at all that the two are dating. The rumor-debunking site described OK! Australia as untrustworthy, noting that the tabloid later released reports that Pitt got back together with Aniston.

This claim seemed to stem from a 2017 New York Post story that said Pitt and Miller were "doing some serious flirting" at "The Lost City of Z" premiere in Los Angeles. Pitt was one of the producers of the movie, while Miller co-starred in the flick.

At the time, a spokesperson for Pitt told Gossip Cop that there is no truth to these claims. NY Post also put out a report that Miller herself said rumors of them flirting were "predictable and silly."

Unfortunately, the rumors of Pitt and Miller dating didn't stop there. In July 2017, Us Weekly also claimed that the two stars were keeping their relationship a secret. Following this, Life & Style magazine claimed that Pitt and Miller's so-called relationship was "heating up." At the time, People magazine confirmed that the two were not in a relationship after doing some digging.
