Ashton Kutcher dispenses credit card advice

If you missed the 2011 Teen Choice Awards Sunday night, you missed Selena Gomez winning five awards, her boyfriend Justin Bieber getting four, a Harry Potter tribute -- and some excellent personal finance advice from Ashton Kutcher.

After he took his surfboard-shaped award for his role in the movie "No Strings Attached," the casually dressed actor told the boisterous audience, "I want to say thank you, but I also want to give you guys the best piece of advice that I ever got when I was a teenager. And this is actually really serious. STOP SCREAMING I'M TRYING TO TALK SERIOUS STUFF RIGHT NOW.  I'm serious about this. The whole United States needs to hear this. Here's the best piece of advice I ever got when I was a teenager: Don't ever charge anything on a credit card if you don't already have the money in the bank to pay for it."

And with that, he broke into an a cappella version of Katy Perry's "Teenage Dream" that had the audience singing along.

"Thank you for the award and the love," he tweeted  a bit later to his 7,359,594 followers on Twitter. "And I'm serious about the credit card thing."

I'm not accustomed to quoting The Hollywood Gossip website, but they put it well. Alluding to the role he'll play this fall in "Two and a Half Men," they said, "Kutcher is already a better role model than Charlie Sheen."
