The singer, who makes her acting debut in 'Smokin' Aces', dreamt of being famous when she was growing up in the tough Manhattan neighbourhood Hell's Kitchen.
Alicia told Britain's Guardian newspaper: "I always knew it was in my future. I grew up around the theatre. My mother is an actress. Its in my blood, it's in my spirit and my fabric of who I am.
"I was always enamoured of the way people would come into the theatre as one person and three hours later emerge as a new one. I was just waiting for my time." The Grammy award-winning musician insists the one role she will never play is a singing pianist.
Alicia, who plays a lesbian assassin in 'Smokin' Aces', said: "One of the main goals when I entered the world of film was not to play a singing pianist.
"It was important for me to start out doing something unexpected, totally out of my comfort zone, and that's why I chose 'Smokin' Aces'. I don't want to play myself." The 26-year-old feels she connected to her character, Georgia Skyes, who pretends to be a prostitute while working as a hitwoman.
Alicia said: "She is powerful and intelligent, the brains of the operation, the sensible one. She is meticulous. Her mindset is very focused. In those ways I am very much like her."
