Billy Joel opens up about fallout with Elton John over ‘hurtful’ rehab remark: ‘There was bad blood’

Billy Joel and Elton John haven’t always seen eye to eye.

During the newly released second part of HBO’s “Billy Joel: And So It Goes” documentary, Joel revealed how John’s public push for him to enter rehab caused a major rift between the two music superstars.

“Elton had made a comment that he thought I needed real rehab,” the “Movin’ Out” singer said in the new doc. “He chalked it up to, ‘Oh, he’s a drunk.’ And that really hurt me.”

“I said, wait a minute? Don’t you know me better than that?” Joel, 76, added. “And there was bad blood for a little while. There was a dovetailing of things that happened during that time.”

The “Piano Man” singer was referring to an interview John, 78, gave Rolling Stone in 2011 shortly after the pair toured together.

After John claimed that he and Joel had “so many cancelled tours” because of “illnesses” and “alcoholism,” he suggested that the “Captain Jack” singer seek real help.
