The show of togetherness follows weeks of speculation that the pair's long-term friendship has blossomed into romance.
Kate and Jamie were often seen out and about together in New York as they drummed up interest for Fantastic Four, which bombed at the box office after it opened earlier in August.
Then 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 on the beach with friends.

Both single: Kate split from her long-term boyfriend Max Minghella in August last year, while Jamie has a son with estranged wife Evan Rachel Wood
'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.
However an insider told E! News back in May: 'They are the very best of friends, long-time friends. Nothing more.'

Belt up in a military mini skirt by Louis Vuitton
Day after day over the summer, Kate Mara gave us killer looks while promoting her latest flick, The Fantastic Four.
When speaking of 'fantastic' we can't help but use it to describe this belted, utilitarian style Louis Vuitton skirt Kate wore with a delicate lace top while arriving in New York.
The simple A- line symmetry of the skirt that cuts high above her knees also features double belted military embellishments. The exposed zipper adds an edge to the flirty silhouette.
We love the distinct contradiction in pairing a feminine lace top with something this strong and uniform.
Kate's skirt hails from LV's Fall RTW collection which means it hasn't hit the racks just yet. So we've sourced some similar selections in our edit below to hold you over in the meantime.
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.
