Forget about that old joke about how Fred Astaire was great but that his dance partner Ginger Rogers did everything he did, but “backwards and in high heels.” And, if you can, put those recent videos of 60-year-old Lenny Kravitz working out in Jeans and boots out of your head too, because Miley Cyrus just revealed that she’s got them both beat.

“My mantra is, like any athlete, ‘Practice how you perform,’” Cyrus told W Magazine in its current cover story. “So that’s why I practice in my heels. The gym looks really tough, but then I’ve got my ivory Gucci slingbacks because they remind me of Marilyn ­Monroe. I train in heels, mostly.”

In addition to squatting in slingbacks, Cyrus said she also works out in her more glamorous stage attire because she wants to bring some feminine energy to the typically grimy, bro-ish gym experience. The singer — who said her sobriety is a big part of her “extremely clean” lifestyle — further explained, “I’m interested in feminizing the workout space, because so much of the workout equipment is ugly.”

In addition to revealing how she ended up on old friend Beyoncé’s “II Most Wanted” Cowboy Carter track earlier this year, Miley also dove into how the two women have been had mothers who’ve been involved in their careers over the years.

“Like her mom, Ms. Tina, my mom is also an M.T.: Mama Tish,” Cyrus said. “A lot of people call her Mom, in the way that Ms. Tina is almost not just a mother to Beyoncé, but to Beyoncé’s fans as well. Both of us grew up, in our own way, with moms who were everything. My mom was my makeup, hair, seamstress, styling, tour manager — like, the actual manager. The word ‘mother’ is the most all-encompassing word. The mother can be RuPaul; the mother can be Beyoncé. Our fans call us ‘mother.’”
