Kate Mara rests her head on shirtless Jamie Bell as Fantastic Four co-stars continue to fuel dating rumours
Their close friendship off the screen has ignited romance rumours.
And Fantastic Four co-stars Jamie Bell and Kate Mara were doing very little to dismiss the speculation when they snuggled up on the beach to watch the full moon in Malibu.
On Sunday, stylist Johnny Wujek Instagrammed a photo of his gal pal Kate, 32, resting her head against the 29-year-old's bare chest.

Romance under the moonlight? Jamie Bell and Kate Mara did little to dismiss romance rumours when they cuddled up on the beach in an Instagram photo shared by stylist Johnny Wujeck on Sunday
The sculpted actor looked smitten as he placed a hand upon Kate's head
'Celebrating the Full Moon in Malibu last night w/ this lot of Goof Balls. #ilovemyfriends #crystals&tequilla,' Johnny captioned the picturesque image.
Both clutching what appeared to be a glass of white wine, the pair dressed casually for their festive outing.
They have great chemistry! Kate and Jamie were spotted together in New York City in August
While Kate sported a white tank top and black shorts, her rumoured romancer wore little more than swimming trunks and a chain necklace.
The pair have been brewing speculation that they are more than just friends as of late.
Kate and Jamie were often seen out and about together in New York City as they drummed up interest for Fantastic Four, which bombed at the box office after it opened earlier in August.

However an insider told E! News back in May: 'They are the very best of friends, long-time friends. Nothing more.'
Jamie has a son with estranged wife Evan Rachel Wood; the pair separated in May last year after 19-months of marriage.
The couple previously dated in 2005, before splitting a year later. But they rekindled their romance in 2011, leading to their wedding in the October of 2012.

In a statement announcing the split at the time, a spokesperson told Us Weekly: 'Evan Rachel Wood and Jamie Bell have decided to separate.
'They both love and respect one another and will of course remain committed to co-parenting their son. This is a mutual decision and the two remain close friends.'
Kate, meanwhile, split from her long-term boyfriend Max Minghella in August last year.
