Scarlett Johansson is fed up of being "an object of desire."

The 29-year-old star, who is pregnant with her first child with her French journalist fiance, Romain Dauriac, plans to embrace the aging process and claims she feels less pressure to look perfect as she gets older.

"I don't want to be the ingenue any more. That part I'm happy about. It's nice to be glamorous, but I don't want to always have to be trendy and glamorous and an object of desire. I don't want to be stuck in that forever. Because it doesn't last," she said.

But Scarlett also told The Weekend Australian magazine that she believes that Hollywood's leading men aren't subjected to as much criticism: "With [male actors] it just doesn't happen the same way. You can be every woman's fantasy and nobody thinks twice about the fact that you have eight kids or whatever."

The Avengers star previously admitted she hopes that she'll be able to juggle motherhood and her career: "I want to be able to have it all. Selfishly."

Scarlett, who started her acting career as a child, recently claimed she wouldn't be able to cope with her celebrity status if she had been a teenager now. "I feel very fortunate that I was able to have a bit of a smoother transition into my young adulthood without having people videotaping me," she said.
