Celebs always fess up about their drug use. The rule, though, is that it always has to be retrospective. They are always "clean now." I'm not saying this as a put down towards George, I'm just sayin'. Look at Liza. Doesn't she do the same thing after a rehab?
Apart from the legal aspects and alleged potential detriment to one's career, it just seems a bit too personal to tell a reporter "I'm on drugs again."
I just hope he doesn't lose his residency over this. He seems to like it here and we like having him.
