Stewart opened up about the feud in a recent interview with Chris Evans, not to be confused with the actor.
“We don't talk to each other anymore,” the “I Don’t Want to Talk About It” singer said on Evans’ “How To Wow” podcast.
The rocker added: “Big falling out.”
Stewart claimed he emailed John inviting his sons Zachary, 9, and Elijah, 7, to come over to play football along with his sons Alistair, 14, and Aiden, 9, and didn’t get a response.
“Last time I emailed him I said, ‘I've got this football pitch, would you like the boys to come up?’ You know, cause they both love football,” he said. “You don’t have to come, but if they want to come play on this they’re welcome.”
Stewart added, “[He] never got back to me.”
The rocker didn’t hold back despite trying to mend his relationship with his once “very close” friend John.
Stewart praised the Freddy Mercury biopic “Bohemian Rhapsody,” but said the “Rocketman” biopic about John didn’t live up to its potential.
“It was OK, I just wished it hadn’t been a musical. I mean, the dancing outside the council house made it a bit ‘Mamma Mia,’” he said.
The rocker previously criticized John’s “Farewell Yellow Brick Road” tour and the biopic, leading to a fall-out between the friends.
On “Watch What Happens Live” with Andy Cohen in 2018, Stewart called the farewell tour “dishonest” and “not rock and roll.”
He added, “If I retire, I won’t make an announcement. I’ll just fade away. I don’t think this is a big deal, it stinks of selling tickets.”
In 2019, the “Sailing” singer once again discussed the feud in a BBC interview with Dermot O'Leary.
“I do love Elton, only we're not talking at the moment. We've had a spat,” he said. “I criticized his tour as being money-grabbing.”
Stewart also said “Rocketman” was “not very flattering” and didn’t live up to “Bohemian Rhapsody.”
