Singer Madonna has flaunted her cleavage in a photograph shared on a social networking platform, but it is her unshaven armpits that are drawing attention.

In a recent selfie from Madonna on Instagram, she is seen wearing a lacy revealing top with her cleavage showing, and she has raised one of her arms to flaunt her armpit hair growth.

`Long hair...... Don't Care!!!!!! #artforfreedom #rebelheart #revolutionoflove (sic),` she captioned the photograph.

Earlier, she had once revealed skipping her armpit shaving routine.

`I saw how popular girls had to behave to get the boys. I knew I couldn't fit into that,` she told Harper's Bazaar in 2011, adding: `So I decided to do the opposite. I refused to wear makeup, to have a hairstyle. I refused to shave. I had hairy armpits.`
