Scarlett Johansson has denied claims that she acted like a diva on the set of Justin Timberlake's new music video.

The actress filmed her appearance for the What Goes Around... video after Christmas, but hit headlines for the wrong reasons when she was accused of throwing a tantrum because she couldn't smoke on set. Reports also claimed that Scarlett's bodyguard banned crew members from eating in front of her.

Responding to the rumours, Johansson's publicist Marcel Pariseau told the New York Daily News: "Scarlett is always respectful of other people. Also, Scarlett doesn't have a bodyguard."
