She added: “This image also shows the complete differences between them.
“Princess Eugenie is looking straight into the camera, authentic smile (slight creases at the eyes) but Princess Beatrice is completely different.
“She is looking into the camera but she has a fake smile, there are no creases around her eyes.
“As well as that, she is holding onto Princess Eugenie in a manner of protection.
“She does not want to have her image taken, she is trying to hide from the picture by placing her sister in front of her.
“They have a true bond and authentic and intimate relationship with each other, but, Princess Eugenie is happy to be in front of a camera and Princess Beatrice is definitely not comfortable being in front of the camera.”
