Are Daisy Ridley and Tom Bateman indeed an item? The English actress and her "Murder on the Orient Express" co-star just added fuel to rumor that they're dating after they were spotted together at the after-party of "Star Wars: The Last Jedi" U.K. premiere on Tuesday night, December 12.

Daisy opted for a low-key look in a casual gray hoodie as she kept close to her rumored new boyfriend, who looked sharp wearing a gray blazer over a black shirt. He looked in good spirits as he flashed a smile on his face. The pair looked as if they already had a heap of mutual pals between them as they both were seen waving off people who headed home.

It marked the rumored new couple's first appearance together after news of their romance broke in early November. In an interview, "Murder on the Orient Express" producer Judy Hofflund let slip about their alleged new romance, suggesting that their love might have been blossoming on the set of the recently-released film.

When asked if any cast members of the Kenneth Branagh-directed thriller got close on the set, the producer responded, "Something kinda happened with Tom and Daisy, right?" She then said, "That's public news," before adding, "I should keep my mouth shut. Oh well."

Tom was then asked if he got close to any of his female co-stars and he replied, "I'm absolutely not going anywhere near that! But nice try." Addressing Judy's comment that he and 25-year-old Daisy were a thing, the actor added, "They like to create a buzz, they've got to otherwise no-one will come and see the movie!"

Reps for Daisy and Tom haven't responded to the romance rumor. The "Star Wars" actress, who previously dated Charlie Hamblett, also refused to comment last month when she was asked by press if she's currently dating someone. "I'm not saying," she coyly responded at the time.
