To Belinda Carlisle's fans, the gorgeous Go-Go appeared to have it all. She led a charmed life complete with musical success, a great marriage and unmatched beauty. But underneath it all, the singer has had her share of struggles. "I hit a lot of bottoms," she tells PopEater while discussing her searing new memoir, 'Lips Unsealed.' Those lows had an awful lot to do with a cocaine habit that grabbed hold of her for 30 years. Now 51, she's been sober only five years. "I don't know why it took me so long," she says. Her inspiration? The thought of her teenage son, Duke, whose dad is Morgan Mason, one day finding his mom dead of an overdose. "That's pretty low," she tells us. "You can't be my age and doing the amount of cocaine I was doing."
