Singer/actress Hilary Duff has used the opportunity as guest editor of magazine Seventeen to hand out financial advice. Duff, who turned 19 last week, recently edited the October issue of the teenage girls' magazine and she decided to issue guidelines on how to use credit cards.

She says, "So many of my friends have started getting credit cards, and the banks don't really tell you how this works, like 'Do this, but don't do that.' So it was important for me to put financial info in there, to let kids know that you have to pay attention to certain things and not fall into a trap.

"It's only been within the last two years that I started to get interested in my business and my money and how investments work. I had no clue before. But I've learned so much just sitting with my business manager."
