It sure looks a lot like love. Actors Shia LaBeouf and Kate Mara were spotted looking chummy during a visit to the Happiest Place on Earth, Disneyland, and Disney’s California Adventure Park, in Anaheim, California, Sunday. Their theme park visit comes just a month after it was announced that they would co-star in the film “Man Down,” the Daily Mail reported.

“They were very close to each other from time to time,” one witness told E! News of their six-hour outing. “At one point they were holding hands and they were always looking at one another in the eyes.”

When LaBeouf and Mara weren’t walking arm-in-arm, the actors enjoyed their day in the sun by taking in some of the park's thrill rides. They were reportedly accompanied by one of Disney’s VIP guides and an unidentified young boy during their visit.

“They appeared to be having fun, enjoying the company,” said another eyewitness. “They tried to stay low key.”

So, is Shia dating Kate? While the duo have yet to say whether their Disneyland outing was more than a platonic venture, LaBeouf, 28, does appear still to be linked to his former “Nymphomaniac” co-star, actress and model Mia Goth, 21. The couple was last seen together in Los Angeles in September, E! News reports.

While LaBeouf might still be romantically attached to his former leading lady, Mara, 31, famous for her role in the Netflix series “House of Cards,” is recently single. Us Weekly reports that the actress split from her longtime boyfriend, actor Max Minghella, 29, in August.

Variety reported that LaBeouf and Mara had signed on to to star alongside Gary Oldman in “Man Down,” a Dito Montiel-directed psychological thriller, last month. The feature will follow the story of an Afghanistan war veteran and his search to find his family in a post-apocalyptic America. The film, which starts production in New Orleans later this month, is scheduled to open in September 2016.
