The 74-year-old rocker, who plays Páirc Uí Chaoimh in Cork tonight, told the Daily Mirror, ''I haven't seen the Elton John biopic, but I'd love one of me.''
Speaking at a party to mark London nightclub Tramp’s 50th anniversary party, which he attended with his wife Penny Lancaster, Stewart added that there is still rivalry between himself and Elton dating back to the seventies.
''We have been in contact with each other a lot lately, bitching everybody out. We are still competitive. We text back and forth... how many albums I've sold and how many he's sold. I'm winning.''
Stewart, who made an emotional appearance on The Late Late Show last March, also had a pop at Elton’s upcoming retirement tour, saying it was "dishonest" and "stinks of selling tickets".
He also said he was "winning" when it came to their recent albums’ chart performances, with Rod’s Another Country selling three times as many copies as 72-year-old’s Elton’s most recent album Wonderful Crazy Night.
"We have been in contact with each other a lot lately, bitching everybody out. We are still competitive," Stewart said. "We text back and forth… how many albums I’ve sold and how many he’s sold. I’m winning."
He also addressed the touchy issue of Elton’s hair. "I’ve still got it, unlike a couple of my mates in the music business. I am not going to mention any names."
Asked about Elton, he said "It’s sewn on."
He also revealed he bought his rival a full-size sit-under hairdryer for his 50th birthday in 1997, with a message saying: "The only thing I forgot to buy was the hair to go with it."
