Johnny Depp's girlfriend Amber Heard has all qualities of being a diva. "The Rum Diaries" starlet is in the showbiz profession but she apparently had a difficult time when people were looking at her as she filmed scenes for her upcoming movie in London, a new report claims.

Depp's beautiful girlfriend is in London since a couple of weeks to shoot for a crime thriller "Fields" with co-star Billy Bob Thornton. The Mail Online reports that the entire shooting for the movie had to be halted after the 27-year-old Heard expressed her discomfort with bystanders looking at her as she shot scenes.

"There were some people watching the shoot outside, then Amber came out to film," an eyewitness on set told the Mail Online. The actress was not comfortable with one particular man who was watching the shooting.

"Right in the middle of the scene she stopped and said, "How am I supposed to do this when all I can see is that guy in my eyeline?" The production also helped Heard. They shielded the man's view with the help of a screen so that the shooting would go on without any distractions.

Depp's girlfriend has been very particular of the fact that she does not like media attention. The 27-year-old has been dating the 50-year-old "Pirates of the Caribbean" star Depp since 2012.

Amber Heard has also graced the covers of "Harper's Bazaar" Russia magazine's November 2013 issue, which is out on newsstands now. Amber shows off her envious curves in a red, white, and blue coloured combination dress. While her beau Depp was sported with a different look - blonde long hair while attending the 2013 BFI London Film Festival Awards in London, England.

Amber's new film "Machete Kills," - a multi-starrer with singer Lady Gaga, is now in theaters. "Machete Kills" director, Robert Rodriguez, is all praises for the star.

"I've always loved Amber Heard. I finally met with her. It was early on in the process, I haven't usually even finished the script yet when I meet with people," Rodriguez told Philly.com. Have you watched "Machete Kills" yet?
