The music icon talked to ET about Prince Harry's wedding and collaborating with Miley Cyrus on the red carpet at the 2018 GRAMMYs.
Elton John is making a bid for the Best Dressed list at the 2018 GRAMMYs, outdoing even himself with a blue, gold and red sequined Gucci jacket, matching glittery glasses and bedazzled rings spelling out "ELTON."
"It's pretty fabulous," the music icon told ET's Cameron Mathison on the red carpet. "That's what I'll be wearing for the next three or four years, and I'm very excited. I started my career in a flamboyant way, and I'm going to end my career in a flamboyant way."
The 70-year-old singer announced his retirement last week, though it won't be until after completing an extensive, years-long farewell tour that will visit "every continent in the world." Gucci will be costuming him for the tour, and John promises the show will be both emotional and fun.
"It'll be the best produced show you've ever seen me do," he said. "It will be very, very emotional and it will go through the whole gamut of my career. And it's going to be a lot of fun!"
First, he will perform on the GRAMMYs stage with Miley Cyrus, two days ahead of his "Elton John: I'm Still Standing -- A GRAMMY Salute" tribute concert. "I've always wanted to work with her," he revealed. "I love my women to be feisty."
"She can sing like a bird, and it's going to be so exciting," he explained. "I've only ever done duets at the GRAMMYs -- and that's the whole point of coming to the GRAMMYs and doing something with Eminem, with the Backstreet Boys, with Ed Sheeran, Gaga and now Miley."
Between his "Farewell Yellow Brick Road Tour" and spending quality time with husband David Furnish and their two sons, will the family have time to make an appearance at the upcoming royal wedding? John recently talked about how "totally in love" Prince Harry is with fiancé Meghan Markle, so will he get invited or, perhaps, even perform?
"I have no idea. No one's been invited yet," John told ET, which Furnish exclaimed, "Crossing our fingers!"
The GRAMMY Awards air on CBS on Sunday, Jan. 28.
