The 35-year-old actress - who has a three-year-old daughter Olive and another girl, aged around eight months, with spouse Sacha Baron Cohen - was amazed to be refused alcohol and taken to a special room at the first showbiz event she attended with the 39-year-old British funnyman, who she has been in a relationship with since 2002.

She said: "My first Hollywood party was awesome. It was for the director Sofia Coppola and was just walk-to-wall with shiny, fabulous people.

"I came to the front door with Sacha, and the hostess goes, `Sacha, you go through to this room and you come with me.`

"And she grabs my hand and takes me to this room filled with 12 year olds - not even 15 year olds! - and goes, `Sit here. Would you like a drink?` So I go, `Can I have a glass of wine?` and she goes, `No, you cannot.` She thought I was Sacha`s daughter, basically."

The `Rango` star also admitted she doesn`t usually enjoy celebrity parties because they are so tame.

She told Elle magazine: "Most people don`t know that Hollywood parties end at 10pm. I`d rather see a movie."
