They may be part of the Fantastic Four, but it seems that Kate Mara and Jamie Bell also make for a delightful duo.

Mutual friend and stylist to the stars, Johnny Wujek, shared a photo of himself and a group of friends on the beach in Malibu on Sunday. In the snap, Mara, 32, and Bell, 29, – who split from his wife Evan Rachel Wood last year – are seen getting cozy with her hand rested on his chiseled chest.

Questions regarding whether or not they are more than friends arose when the two appeared at this year’s Met Gala together and were spotted holding hands on the red carpet.

The pair haven’t commented about whether they are dating. However, the film’s screenwriter, Simon Kinberg, told PEOPLE that the cast was like a family and compared the chemistry on set to that of Brad Pitt and Angeline Jolie Pitt.

“I think it’s hard to fake chemistry,” Kinberg said. “It goes back for me to Mr. and Mrs. Smith, which is the first film I ever worked on and it was like these two people are meeting for the first time and if you connect with somebody, you connect with them.”
