Portman fears tripping on red carpet

Actress Natalie Portman has confessed that she secretly panics about tripping while walking on the red carpet in front of everyone.

It's tricky, she believes.

"It's a very serious game. I remember my first red carpet, I felt like I was wearing a costume, it was hilarious. Nowadays, I'm used to it. You just need to look happy even if you're wearing uncomfortable shoes or a dress you regret having chosen," France's Madame Figaro magazine quoted Portman as saying.

"My top tip? Looking confident and calm. My biggest fear? Tripping up. When I was pregnant, it was an obsession, I kept repeating to myself, 'Don't fall, don't fall'," she added.

The 32-year-old has also become the new face of Rouge Dior lipstick and says advertising a red lipstick was an obvious choice for her.

Asked what the colour means to her, she said: "Passion, of course. Confidence, strength, seduction, femininity. It's the colour of brunettes. When I put red lipstick on, it's because I want to be admired... by my husband."
