Scarlett Johansson sweats on the red carpet!

Sydney (ANI): Actress Scarlett Johansson has admitted that nerves often get the better of her, whenever she has to make an appearance on the red carpet.

She said: "I like the getting ready part. I like the hair and the make-up and the pretty dress... It's just getting on the red carpet I just instantly flop sweat. It's a weird chemical reaction I have somehow to the red carpet. I don't know what it is. Maybe it's just the carpet itself."

The star, 25, further added that she suffers a similar reaction when singing live, reports The Sydney Morning Herald. She added to US TV talk show host Ellen DeGeneres: "I flop sweat then too. I probably need a shot to stop that." Flop sweat is nervous perspiration caused by a fear of failure before an audience.
