Jessica Alba feels ''more saucy'' than she did 10 years ago.

The 33-year-old actress - who has children Honor, six, and Haven, two, with husband Cash Warren - thinks she has more confidence in herself now than when she shot 'Sin City' 10 years ago.

She said: ''I feel much more grounded, much more comfortable, much more saucy. Then I was a girl, I was timid, I was afraid, I was so insecure and now I'm a woman and it's different... I'm more uninhibited.''

Jessica reprises her 'Sin City' role of Nancy Callahan in 'Sin City: A Dame To Kill For' and promised fans she has a bigger role this time around.

She told the forthcoming issue of Britain's GQ magazine: ''There's more of me and I do more than I did in the first one. I have a bit more of a character arc in this one. There's more dancing, but the dancing's really connected to the story. Nancy's a bit of an alcoholic and a bit of a mess and she's depressed and angry. The dances in the movie reflects where she's at.''

Meanwhile, the brunette beauty also paid tribute to her 'Into the Blue' co-star Paul Walker, who died in a car accident last November, praising his kind and respectful ways.

She said: ''He had a real childlike innocence and he was game to try anything or do anything. He treated everyone with respect and love. He was never treating anybody differently because of who they were. He was really a guy's guy. And loved his daughter so much and talked about her all the time. He never cared about Hollywood. He never cared about the hype.''
