Last week, rumor came out that Justin Timberlake finally called it quits with his long-time girlfriend Cameron Diaz. Various spies spoke to the media, claiming they are no longer an item and that the 'SexyBack' singer is already telling people in clubs that he's single and looking.

In which way this is connected to Scarlett Johansson, you will see in just a second. Immediately after the rumor about the Timberlake-Diaz split came out, it was heard that the singer wanted sexy actress Scarlett in his latest video (now shooting) for the third single release, 'What Goes Around... Comes Around', taken from his second album.

The 'Black Dahlia' star accepted Justin's offer and, inevitably, the media began trying to link the two gorgeous stars romantically. Sources say that, on the set, Justin couldn't take his eyes off Scarlett, that he refused to pay attention or to talk to anyone else and that they were inseparable and looking 'very much in love'.

A spokesperson for the actress released a press statement yesterday but he refused to address the rumors about a blooming romance between Scarlett and Justin. Instead, he addressed those rumors that had her acting all diva-like on the set of the shoot, rubbishing them completely.

Sources from the set said that Johansson pissed off everyone present at the location, with her absurd demands and her hysterical behavior. Apparently, she was so upset because she wasn't allowed to smoke in between takes that she began shouting at everybody 'How come we have fire dancers, but I can't smoke?'.

Another thing that she couldn't stand was people eating in front of her, so she had her bodyguards chase away anyone who dared come too close to her with food in his/her hand. But Marcel Pariseau, Scarlett's publicist, says all these are just lies. 'Scarlett is always respectful for other people and never made this statement. Also, Scarlett doesn't have a bodyguard', he is quoted as saying by the 'New York Daily News'.
