Last month, she told her Instagram fans she had faced her fear of crabs to film a scene.
She revealed: “Just so you know, I’m terrified of spiders, it’s a real phobia and people who have the same phobia will understand crabs are like huge massive spiders.
“It’s even worse it’s like a nightmare so I did the scene and I was decomposed, gone, dead inside.”
The actress then showed fans a behind-the-scenes video of her practising holding the crab.
“I’m literally crying and terrified,” she said of the moment. “But, I did it the first time, I was so proud of myself.”
