Leif Garrett knows what Justin Bieber is going through. But the 1970s-era teen idol hopes that Bieber ends up avoiding the same mistakes. "Do not believe your own publicity," the now 51-year-old actor warned in an interview with FoxNews.com when asked if he had any advice. "Sussing out who your real friends are is full-time work."

The notorious bad boy and his crew were targeted by a drug-sniffing police dog after jetting into Ft. Lauerdale International Airport on Friday to hang with Jay Z and Kevin Hart.
