The superstar opted for a rather daring look and took a photograph in a bathroom mirror for fans.
Madonna seems to be taking style tips from Kim Kardashian these days by falling in love with a very **** pair of boots.
The 56-year-old star continued to prove she won't be getting a blue rinse anytime soon or covering up with saggy jumpers as she flaunted her figure in a selfie.
Posing in front of a mirror in a black leotard and black knee-high lace-up boots, she wrote on Instagram: "Nothing Glamorous about this bathroom but these Gucci Boots are Eeeeevrythang! #rebelhearttour."
She can be seen in the pic without any make-up on looking slightly tired while rocking a wavy blonde hairstyle and wearing black fishnet stockings.
Meanwhile, Madonna recently claimed she will continue making music until she dies because she is so "inspired" to keep working, just like Picasso, who died in 1973.
She said: "I like to compare myself to other kinds of artists like Picasso. He kept painting and painting until the day he died. Why? Because I guess he felt inspired to do so. Life inspired him, so he had to keep expressing himself, and that's how I feel."
The Living For Love hitmaker - who released her latest album Rebel Heart earlier this year - continued to say she doesn't think her creative streak will ever fade because she always wants to inspire others.
She explained: "I don't think there's a time, a date, an expiration date for being creative. I think you go until you don't have any more to say."
The music icon will kick off her Rebel Heart Tour on September 9 in Montreal, Canada and said she has spent "weeks and weeks" choosing a set list because she has so many well known hits to choose from.
She added: "The theme I really truly explore in this show more than anything is love and romance. I want people to walk out like they're feeling inspired and like they've seen something they've never seen before (and) felt something they've never felt before.
"I realize I have 32 years of other songs, so I have to pick and choose. I sit there for weeks and weeks and weeks trying to figure out which of my old catalog I want to do.
"It's a puzzle that we have to put together 'cause thematically the songs -- the old and the new -- they have to go together; sonically they have to go together."
