Sienna Miller has been caught canoodling with her co-star James Franco.
The actress - who is reportedly back with on-off boyfriend Jude Law - was photographed locking lips with the 'Spider-Man' star in Toronto, Canada, last weekend.
Onlookers said the pair - who are in the Canadian city filming black comedy 'Camille' together - looked "very into each other" as they took in a movie, concert and dinner.
It is not the first time Franco, 28, and 'Alfie' star Miller have been caught getting close in public.
The pair also spent a day shopping together and the actor was seen "touching her hair".
Earlier this year, Miller was linked to another co-star, Hayden Christensen.
However, the actress' fling with the 'Star Wars' star - who appeared alongside her in upcoming movie 'Factory Girl' - ended abruptly in April when she dumped him and flew to Los Angeles to try and patch things up with Law.
The British actor and Miller - who have had an on/off relationship since Jude admitted sleeping with his children's nanny last year - were recently spotted on a night out with friends in Hollywood.
Law kept an arm around the 33-year-old blonde while they partied, and even rested his hand on her butt at one point.
