Debbie Gibson knows something about being a teenage star and now she's  sharing her wisdom with today's crop of teen pop stars through her new Web series, 'What Would Debbie Do?'.   Check out what she has to say to some of  the current  teen stars.   

To Justin Bieber: "What are you doing vacationing on a yacht with your girlfriend when [you're] 17 or 18 years old, anyway?"

To Miley Cyrus: "Don't be in a hurry to grow up. Honestly, there's a gazillion years to be an adult. I was hanging onto my childhood for dear life. I was wearing high top sneakers with my dresses, I was like, 'Ya know what? There’s gonna be plenty of years to wear high heels.'"

To Selena Gomez: "The more private you can keep your personal life the better."

What do you think of her unsolicited advice?   Agree or disagree?
