Robert Pattinson vs. Ben Affleck New Movie 'Crush,' Sienna Miller & FKA Twigs 'Flirting'

Several months ago, rumors suggested that things were heating-up between Robert Pattinson and Sienna Miller on the set of their new movie, "The Lost City of Z" -

"They're spending a lot of time hanging out in each other's trailers and often meet up for late-night pub runs. The cast and crew are picking up on the mutual attraction... [Pattinson] threatens to break up with [FKA] Twigs and [she] dares him to. With [Miller] in the picture, no one would be surprised if he made good on his threat" (via Star magazine).

But 29-year-old Pattinson's current engagement to the stunning English songstress seems to be going strong now. Maybe that's because Miller officially moved-on to yet another celebrity crush?

Apparently, sparks are now flying between the 34-year-old blonde bombshell and Jennifer Garner's ex-hubby, Ben Affleck! Both stars are currently filming the upcoming crime drama, "Live by Night." Affleck actually wrote and directed the flick (also starring Chris Messina, Zoe Saldana, and Elle Fanning). According to Us Weekly, "sweet" feelings are blossoming between Miller and the 43-year-old "Daredevil" heartthrob. They were even spotted holding hands around the studio.

The "American Sniper" beauty tends to date several of the men she works with in Hollywood. Her relationship with "Alfie" co-star Jude Law ended in 2006. She then indulged in a public fling with married actor, Balthazar Getty;. She was romantically involved with Tom Sturridge, for awhile, and they share a young daughter together named Marlowe Ottoline Layng. But they officially broke things off in July 2015. Most recently she was also linked to 52-year-old Brad Pitt, although he's happily married to Angelina Jolie (via Movie News Guide).

But will her close "friendship" with Affleck actually progress?

Well, are MstarsNews readers at least relieved that she didn't come between R-Patz's love for Twigs? Sound-off in the comments section below!
