Rob Lowe reflects on 'rock bottom' moment which led to sobriety journey

During an interview with People, the Parks and Recreation actor detailed the point at which he realised he had to stop drinking when he was 26. In what Lowe described as his rock "bottom," he recounted how he came home from partying one night and listened to a voicemail from his mother who informed him that his grandfather had suffered a heart attack. Instead of calling her back, the star continued drinking.
