Josh HartnettJosh Hartnett has denied there is anything going on between him and his 30 Days of Night co-star Amber Sainsbury.

Josh was spotted with the woman, who has been identified by Australia’s Daily Telegraph as Amber, repeatedly in Sydney over the weekend, fueling the rumours that he’s split from girlfriend Scarlett Johansson.

However, on-set sources have revealed that Josh is adamant there is nothing going on, that the pair are just friends and that he’s met her boyfriend.

An onlooker spotted the pair after breakfast at a cafe in the city on Sunday morning: “Josh got jumped on by a few different people to get photos taken, so she went outside the cafe. But when he eventually went out he put his arm around her as they walked across the street. There was a level of intimacy there.”
