Actress Sienna Miller has finally broken her silence on the dating rumours that linked her to Hollywood heartthrob Brad Pitt. Following the Los Angeles premiere of their film – The Lost City Of Z – buzz was that the British-American star and Pitt were spotted flirting with each other.

But the actress rubbished the romance rumours, calling them "predictable" considering Pitt serves as the producer of her new film. The 53-year-old's Plan B production is behind the new film.

"I'm not going to even dignify it with a response," the Live By Night actress said, responding to the gossip reports at a Cinema Society screening of her new movie. "It's predictable and silly," she said.

This comes after Page Six reported that newly-single Pitt was spotted "seriously flirting" with the actress last week.

According to the gossip site, they were "heavily enjoying each other's company" and "were talking to each other all night" while dining with a group of friends at a restaurant near the ArcLight movie theater in L.A.

As reported before, the sensational reports connecting the two stars were based on mere speculations and as far as the "serious flirting" rumours go, "there's nothing to it".

Even Miller is no stranger to these rumours. The 35-year-old American Sniper star has been previously linked to her Alfie co-star Jude Law and Layer Cake's Daniel Craig. Recently, she was said to be dating director Bennett Miller after her split with ex-fiance, Tom Sturridge.

Pitt, on the other hand, has been embroiled in legal proceedings after his ex Angelina Jolie filed for divorce last year. Following the split news, the actor kept a low-profile until recently when he started attending premiere events and awards shows.

There have been speculations surrounding the two since 2015, when the film was under production. "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," she had said.
