But they sparked rumours that they could be more than just co-stars after they were snapped leaving Hollywood's Arclight Cinerama Dome, reports sun.co.uk.

Tyler, 35, wearing a striped top and carrying a brightly coloured satchel, and Cumberbatch, sporting jeans, a blue polo shirt and a grey jacket, smiled as they left together.

They were also spotted together at a post-Emmy awards party at the Sunset Towers Hotel Sunday.
