LOS ANGLES-Scarlett Johansson has joked about having a “huge ego”. The Hollywood star was chosen to be the face of Dolce and Gabbana’s new fragrance The One alongside Matthew McConaughey.

Asked about her latest role, she told the Daily Mail: “ Why am I The One? Because I am an actor and all actors think that they are The One. It’s part of our huge egos and makes us so successful in some areas of our lives and not in others.”

Scarlett also joked about having a sharp sense of humour, following Woody Allen’s comment that she is “wittier” than him.

“Am I the funniest woman in Hollywood? It depends on the time of day but, of course, I think I am absolutely hilarious - that comes with the ego territory of acting,” she quipped.

The 29-year-old, who is engaged to French businessman Romain Dauriac, revealed she is excited to become a mother in the future.

“I would like to have my own family, that would be nice. They say it’s never the right time and I am sure that’s true, but I think you have to plan it like anything else,” she said.

“At some point it is something I look forward to. I am fortunate in that I have had a long career - 20 years - that has been very diverse. So, you know, picking a time to plan a family feels like something that I could do and not feel as though I was missing out,” she added.

Scarlett, who next stars as a computer-generated voice in Spike Jonze’s Her, said she would like to do a silent film.

“I prefer films where I have as little dialogue as possible because then I have greater freedom to interpret my performance. So I would love to do a silent film - that would be wonderful,” she said.
