This would be a seriously hot couple!

Brad Pitt and Sienna Miller were caught doing some "serious flirting" at a private dinner for their upcoming film The Lost City of Z, Page Six reports. There were about 25 other people at the meal, but the sexy stars only seemed to be interested in each other.

The pair were “heavily enjoying each other’s company,” and “they were talking to each other all night,” according to an eyewitness. Not only that, but the actor was “in very high spirits, which he hasn’t been for a long time. He seems to be over a hump.”

This isn't the first time they've been linked, and the British beauty has downplayed their connection before.

“So this is the truth about that: Brad Pitt is producing the movie that I just wrapped, but I didn’t see him. He’s not been to the set. You know, he’s the producer of the film and I’ve met him twice. It’s insane," she previously said about the romance rumors.

In the wake of his nasty divorce from Angelina Jolie, we think a hot hookup for Brad would be the best medicine!
