Sienna Miller stars in several upcoming movies alongside a slew of very attractive Hollywood men - Robert Pattinson, Bradley Cooper, Leonardo DiCaprio, Charlie Hunam, and Brad Pitt's currently producing the highly-anticipated action flick "The Lost City of Z." So, has the 33-year-old English beauty indulged in any romantic flings while filming with these heartthrobs?

Well, Pitt definitely did NOT cheat on wife Angelina Jolie, despite recent rumors. According to Miller, she barely knows the 51-year-old award winner:

"I haven't really read too much about it, but break it down, let's clear it up," the blonde fashionista joked during a recent interview with Sway. "So the truth about that rumour is that Brad Pitt is producing the movie that I just wrapped but I haven't seen him. He's not been to the set, he's a producer on the film and I've met him twice, and yeah, it's insane" (via Vogue UK).

But why didn't she deny ever hooking-up with Kristen Stewart's ex? Pattinson's currently engaged to aspiring songstress FKA Twigs, but he apparently has a little "crush" on Miller (considering they work together so much). Supposedly, their on (and off) screen chemistry's rather intense:

"They're spending a lot of time hanging out in each other's trailers and often meet up for late-night pub runs," an alleged Star magazine insider explains. "The cast and crew are picking up on the mutual attraction."

And what about Miller and her gorgeous "Burnt" co-star? The "American Sniper" lovers heated-up the red carpet at their recent NYC premiere. Still, Cooper's allegedly dating 23-year-old model Suki Waterhouse.

Miller's basking in the spotlight! "The Lost City of Z" hits theaters sometime in 2016 and Ben Affleck's "Live By Night" debuts next October.

Miller was once attached to Jude Law and Tom Sturridge, but is now single.
