The daughter of the late Michael Jackson recently won her first film role in Lundon's Bridge and the Three Keys.
Speaking to Prevention magazine, Janet said: "We've spoken about the fact that you're only a child once. I think there's a time for everything, and now is not the time [to act in films].
"I told her I thought she should enjoy being a kid, possibly go to college - or not - but wait till she turns 18. She's a very tough, smart girl. But it's a cutthroat industry. I wouldn't want my child to do it."
Janet recently revealed that she has started work on a new album, which as yet has no release date.
It was also recently reported that her notorious 'wardrobe malfunction' during the Super Bowl XXXVIII halftime show may be referred back to the US Supreme Court.
