Select photos of the calender shoot, leaked on the Internet, reveal the 27-year-old showing off her hour-glass figure.
The before and after images show that even Jessica's perfect curves got some airbrushing to give her the image of a pin-up girl.
Alba is the latest celebrity to have her images 'touched up.' Earlier, 'Titanic' actress Kate Winslet's was slammed for her airbrushed images in 'Vanity Fair' magazine.
The 'Sin City' star is seen posing in a white strapless short suit with a black belt on the limited edition calender, which were shot by celebrity-photographer Mario Testino.
The leaked photographs of the actress have been posted on various Internet blogs showing an original shot of Jessica posing for Campari, in an image which was later airbrushed, the ‘Daily Mail’ reported.
However, in the picture which is not airbrushed, Jessica has more softer and natural look.
The airbrushed version of the picture seems to have narrowed her chin slightly and added more makeup to give her a pin-up girl look.
