Madonna has had her septum pierced.

The 'Living for Love' hitmaker posed with a new gold nose accessory, which is customised with the letter M, and shared the picture on her Instagram account.

Alongside the image, she wrote: ''You Can't Mess with this lucky Star #b****immadonna #iconic #rebelhearttour (sic).''

The 56-year-old singer is known to embrace unique trends and in her latest music video for 'B**** I'm Madonna' she can be seen flashing her golden grill in her mouth, which she has kept since first showing it off in 2013, when the likes of Justin Bieber and Rihanna donned the fierce look.

The singer appears to follow her daughter's fashion style to keep on-trend and maintain a youthful image, as 18-year-old Lourdes Leon stepped out with a septum ring while shopping in New York City a couple of months ago.

The look - popular with young girls - is a daring move for the 'Rebel Heart' superstar who is the only mature star to embrace the look.

Other pop stars who have worn the jewel include Robert Pattinson's fiancée FKA Twigs, Lady GaGa and 'Keeping Up With the Kardashians' star Kendall Jenner.
