A new feud between superstars is brewing between Elton John and Janet Jackson, but only one of them is actually using their voice … and therein lies the cornerstone of the feud.

Elton has never been one to bite his tongue and he proved that once again when he spoke about Janet and her showmanship with Rolling Stone magazine.

"I say what I feel," the music legend said. "I probably went too far with Madonna [publicly calling her out for lip-synching], and I got very personal and I wrote her — she was very gracious. … You know, f------ music magazines writing a review of Janet Jackson saying, 'This is the greatest show — four and a half stars.' It's f------ lip-synched! Hello! That's not a show! I'd rather go and see a drag queen."

Ouch!

Elton collaborated with Janet in 1999 for "I Know The Truth."

In the same Rolling Stone interview, Elton called out Billy Joel, his frequent touring partner, who the "Rocket Man" has blasted in the past for not getting his drinking under control.

"He's one of the great American songwriters. But I know when people used to say to me, 'You're wasting your life,' I'd go, 'F--- off!' and I wouldn't speak to them for two years," he said. "Billy was p------ [about my public comments], and I understand. But does it mean I don't love him? No, of course not."

The two eventually made up.

In a way, no one should be surprised that Elton is speaking out. This is what he's always done, for better or for worse.

In March 2015 he got into a highly publicized battle with the Dolce & Gabbana partners for their controversial views on "gay adoptions" and in vitro fertilization.

"I call children of chemistry, synthetic children," the fashion designers said, "rented uterus, semen chosen from a catalog."

Elton, an openly gay man with two children, boycotted the brand. His one-time enemy-turned-friend Madonna backed Elton. In a photo posted to Instagram of her in D&G clothing in 2010, she said, "All babies contain a soul however they come to this earth and their families. There is nothing synthetic about a soul!!"
