Madonna shows off diamond encrusted grills as she attends Menton music festival with boyfriend Brahim Zaibat

Madonna showed off her distinctive looking grills when she arrived in the south of France accompanied by boyfriend Brahim Zaibat.
The 54-year-old singer was paying a visit to Menton, a picturesque coastal town close to the French-Italian border and site of the annual Festival de Musique de Menton – a celebration of classical music with performances from a range of global artists and symphony orchestras.

But while then occasion was all about classical music, Madonna also took the opportunity to show off the distinctly urban grills she previously showcased for followers on picture messaging service Instagtram.

The bizarre fashion accessory includes 24 diamonds and an open-tooth design that shows her real teeth underneath.

Evidently delighted with her new mouthpiece, Madonna has since showing them off in a range of shots over the last few weeks, including one in which he appears to be biting down on a sword.

Dressed a little less provocatively than usual in a polka dotted black dress and white cardigan, Madonna was spotted taking in performances from concert pianist sisters Katia and Marielle Labèque and Basque band Kalakan, with whom the singer is close friends.
But while Zaibat looked bright and cheerful in a Comme des Garcons T-shirt, his famous girlfriend looked distinctly weary as they entered the venue for a night of world music.
Indeed, Madonna appeared to be ready for a good nights sleep as she ran a hand through her hair, her eyes downcast as she followed festival art director Paul Thomas Emmanuel into the event, with a grinning Zaibat bringing up the rear.

The Borderline singer added a touch of mainstream glamour to an event not generally known for attracting mainstream celebrities.
But while she was warmly greeted at the event, she’s said to be less welcome in Russia after reportedly violating the terms of her visa by claiming money for a performance in St. Petersburg last year.
According to ABC performers are not allowed to earn money in the country while visiting on a tourist visa.
Lady Gaga has been accused of breaching the same rule while performing in Moscow and St. Petersburg with her Born This Way tour in 2012, but insiders claim real the source of the controversy is their apparent promotion of gay rights while visitors.

‘The Russian government is sending a shot across the bow to Lady Gaga, Madonna, and other performers who are taking up gay rights in Russia,’ Centre for the National Interest executive director Paul Saunders told ABC.
During her concert in Russia, Madonna reportedly told the audience: ‘Gay people here and all around the world have the same rights.’
The comment is understood to have incensed advocates of St. Petersburg’s anti-gay law, which prohibits people to openly talk about homosexuality around minors.
Anyone breaking the law face potential fines, deportation and – in extreme cases – imprisonment.
