The Queen of Pop posted the shot to Instagram on 21 March and, although she's clad in sexy black lingerie, your eye is immediately drawn to her underarm.
And, in case we missed the point of her photo, she added the caption: "Long Hair. Don't care! #artforfreedom #rebelheart #revolutionoflove."
Madonna's picture has certainly sparked a debate about whether hairy pits are a do or don't for women…
A lover of the look tweeted: "She's a hero. That's what I've deduced." Another said: "what's wrong w/ madonna having armpit hair?? it grows there naturally. some of you would be lucky to look good at 55 w/ armpit hair."
Another loyal fan simply said: "Queen of Armpits."
However, not everyone loved the look. A less impressed follower tweeted: "I can never unsee Madonna and her armpit hair photo…" Another said: "Eww Madonna has armpit hair, gross I'm done."
Madonna's armpit photo came as fans around the world celebrate the 25th anniversary of her iconic Like A Prayer album.
