Now, he has apologized.
Adler posted a statement on his Facebook page. In it, he expressed regret for his words and claimed that his emotions got the best of him:
"We had a full press day yesterday and I'd like to shed some light on my comments about the current Guns N Roses lineup. Sometimes my emotions get the best of me when talking about my former band. It’s hard to see your ex in bed with somebody else. We created one of the biggest selling debut albums of all time and it’s no secret that I want to finish what we started 25 years ago and play together at the Rock N Roll Hall Of Fame. The guys that Axl has put together are all great players. They’re not hacks in the sense that they can’t play, they’re all incredible musicians. I just meant that they are not the original lineup. I would like to apologize to Axl, Bumblefoot, D.J., Tommy, Dizzy, Richard, Frank, and Chris for my statement."
