Dame Helen Mirren believes women are under too much pressure to look good.
The Oscar winning actress thinks it's unfair that female stars are given such a hard time by fashion critics to look perfect on the red carpet.
She admits it's a challenge picking the right outfit to wear to high profile events.
She told Graham Norton on his chat show: "There is a lot of pressure about the gown. It's very unfair on us girls, it's uncomfortable and stress-making and then they tell you, 'You look crap'."
The Queen star - who shared a kiss with Hollywood hunk Paul Rudd on the programme - also spoke about filming love scenes and she said she finds them particularly difficult.
She said: "It is so technical it becomes a mathematical thing to be worked out."
However 43-year-old Rudd disagreed, saying filming intimate scenes has been the highlight of his career so far.
Speaking about his role in How Do You Know he said: "The most kisses I've had in a movie was with Jack Nicholson where we played a loving father and son. It was one of the greatest moments of my life."
