Former child star Leif Garrett sympathises with troubled stars Britney Spears and Lindsay Lohan, insisting young celebrities are bound to make mistakes when they're in the public eye so much. Singer/actor Garrett, who has famously battled drug addiction as an adult, hopes the Hollywood starlets can sort out their problems before it's too late. The now-clean 45-year-old says, "It's really tough, what Britney's going through right now, and Lindsay. When you've got the media in your face the whole time it's kind of tough. "We're all human... you make mistakes, and that's what happens. It's just not being publicised." Garrett checked into rehab last year (06) after police found him in possession of heroin in what was the latest of a string of drug-related arrests. After quitting the treatment centre, he was sentenced to 90 days in jail and three years probation in May 2006, but was credited with the time already served in police custody.
