Angelina Jolie has very particular food habits, it is claimed.

An employee of the A-List star has dished to In Touch about the star's "food obsessions" and says Angelina has very different dietary requirements.

The 36-year-old actress is well known for her very slender physique and it is reported she does not have the biggest of appetites.

"Her daily diet varies," a source told the publication. "Sometimes it will be just green tea and nuts. Other days, it will be red meat and red wine, and then, back to tea and some tiny portion of protein."

Another insider also claimed that Angelina sometime requested the same food over and over.

"She became obsessed with soup," an employee told the magazine. "Light soups that didn't have a cream base that became the constant request."

Meanwhile Grazia magazine alleges that the mother-of-six sometimes only consumes 600 calories a day.

"Angelina has been known to start her day with little more than a spoonful of coconut oil and a handful of cereal," a source told the publication about Brad Pitt's partner.

"The worrying thing is that she is so busy, she often forgets to eat."

The insider added that the star would sometimes skip lunch or grab a few almonds or gummy bears on the go, or have a protein-based shake rather than a full meal.

"Then dinner could be something like a lean steak and a glass of red wine," the source said.

"Everyone has been begging her to eat more and she is trying not to get any skinnier, but unfortunately she just doesn't seem to be putting on any more weight."

Angelina has defended her physique in the past saying that she has "always been lean."
