*The son of slain rap icon Notorious B.I.G. sees $20 per week from his Hollywood paychecks, thanks to mom Faith Evans – who rules the purse strings.

Christopher “CJ” Wallace, 14, made his big screen debut in 2009’s “Notorious,” starring as the younger version of his father in a biopic about the slain rapper. This month, he returns to theaters opposite Will Farrell in the dark comedy “Everything Must Go.”

Despite his blossoming Hollywood career, CJ reveals he doesn’t take advantage of his good fortune – Evans keeps his finances under tight control.

He tells the New York Post, “I get $20 a week in allowance. I never really asked if I can take money out and just spend it. (But) there’s nothing I really want to buy at this moment.”

Wallace admits he never considered acting as a career until his grandma, Voletta Wallace, urged him to try out for the “Notorious” part – a role which proved to be a learning experience in more ways than one.

“I didn’t really want to do it, but I did it anyway,” he says. “After I got it, I found out stuff that I didn’t even know about my dad.”

The youngster is now planning to study film at college and will enroll in his first acting course later this year.
