Patti, 77, revealed that when she was singing with the Bluebelles, Elton, 74 - whose real name is Reginald Dwight - was working with her in the studio as a pianist and she used to invite him back to her flat for food.
Although she asked him to bring back the Tupperware container that she gave him filled with leftovers, he never did, and years later he replaced it with a diamond ring.
Speaking on Andy Cohen's 'Watch What Happens Live', Patti explained: "I cooked for him and the band because nobody had any pounds, you know? We were in London. So I would invite them up to my loft every night and give them Tupperware to take home because nobody had food. I said to them at the time, 'Bring my Tupperware to the next show.' They didn't.
“I still have time to find a husband,” LaBelle exclusively tells The Post. “I don’t want a boyfriend. I want a husband.”
The two-time Grammy winner has a sharp memory, recalling how she loved to cook for Richard Pryor, The Rolling Stones and Elton John before he made it big.
“After the show, I’d feed them. I said, ‘OK, you guys can take Tupperware packages with food in them, it’ll last you for a week,” she said.
The “Tiny Dancer” singer never returned LaBelle’s food containers and she never forgot it, admitting she was green with envy over his success.
“He called me in Philly, because he kept my number. He said, ‘Patti would you like to come to see my show tonight?’ So I said, ‘Yeah, who are you opening for?’ He said, ‘I’m not. I’m Elton John now,” she recalled. “I said, ‘You’re a liar.’”
She continued: “I was so mad that he made it before I did. So I said, ‘OK punk, where’s my Tupperware?’ I swear to God, that’s all I wanted.”
She never got the Tupperware back, but years later, Elton John made up for it after they recorded “Your Song” together in 2005.
“He took [his jewelry] off when we finished. I said, ‘Elton, here’s your jewelry,’ and he said, ‘No that ring is for you for the Tupperware that I’m never gonna give you back because I can’t get it. But you can have that diamond.’ So he gave me a ring and I still have it.”
