After Sienna Miller and tom Sturridge called off their engagement in July, the heartbroken actress flew to Ireland to begin filming The Lost City of Z with her former fiancé’s best friend, Robert pattinson. “rob has been a delightful distraction for Sienna,” says a source close to the actress, 33. “they’re spending a lot of time hanging out in each other’s trailers and often meet up for late-night pub runs.
Rob has even jumped in to help out with her daughter, Marlowe. they’re both treading carefully, but the cast and crew are picking up on the mutual attraction.” As for rob’s own engagement to singer FKA twigs, it’s off to a rocky start with wedding planning on an indefinite hold. “they’ve been on and off for months,” says a pal of the Twilight star, 29. “they fight. rob threatens to break up with her and twigs dares him to. but now, with Sienna in the picture, no one would be surprised if he made good on his threat.”
