Scarlett Johansson is glad she found fame 10 years ago.

The 29-year-old actress - who shot into the limelight after starring in 'Lost in Translation' in 2003 - doesn't think she would have been able to cope with her celebrity status if she had been a teenager now.

She explained to USA Today: ''When I was first becoming more publicly recognisable, I was probably about 18 or 19 and that was 10 years ago - I look at kids that are 18 or 19 now and coming into the spotlight, that would be excruciating. 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.''

The blonde beauty - who is expecting her first child with her fiancé Romain Dauriac - insists she'll never join any social networking sites because she doesn't want to be criticised for everything she posts online.

She said: ''It seems much more complicated now. If you're constantly feeling like you're being hunted, that's going to drive you nuts. You have to be wise about the choices you make.''
