Actress Sienna Miller has finally broken her silence on rumours saying that she's getting flirtatious with Brad Pitt.

Miller, who was rumoured to have a special relationship with Pitt as they are working on a project together, set the record straight on the allegations and said she didn't "read too much about it," reports aceshowbiz.com.

Pitt is the producer of the upcoming action adventure biographical movie "The Lost City of Z", which stars Miller.

"The brilliant thing about that rumour is that, yeah, I haven't really read too much about it. 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," Miller said on rapper Eminem's hip-hop channel SiriusXM's Shade 45.

The cheating allegations were first reported by In Touch magazine which claimed that Angelina Jolie was "consumed by jealousy" over Pitt and Miller's professional relationship.

Miller then claimed the idea that she's dating her film's producer whom she met only twice was crazy.

"You know he's the producer of the film and I've met him twice - it's insane," she said.

In addition to Miller, a source close to Jolie and Pitt had previously denied the affair rumours as saying that it "never happened."
