Katy Perry spent $1,000 (RM3.3k!) on a diamond-encrusted grill for the MTV Video Music Awards.
The 'Roar' singer enlisted rapper-turned-jewellery designer Paul Wall to create a shiny mouth accessory for her to sport on the red carpet at the awards ceremony in New York City on Sunday (25.08.13).
Katy, 28, followed in the footsteps of Miley Cyrus, Madonna and close pal Rihanna by flashing her new grill, which is multi-coloured and has the title of her new single etched into it.
Diamond-encrusted grills became all the rage with rappers in 2005 - with Nelly even penning a song about the lavish mouthpieces - but they have more recently become common amongst pop's female elite.
Paul - who also designed the gold grill Miley has been sporting in recent months - thinks Katy and the 'We Can't Stop' hitmaker have started a new trend among young girls and he has already seen an influx in orders for custom made pieces.
He told the New York Daily News: ''I think it's dope. I like it. I like seeing girls with grills, it's something different.''
Meanwhile, Albert Levy - manager of Contessa Jewelers, who designed Madonna's grill - added: ''Just this year in the summertime, I think Miley's the one that did it. We've been doing it for all the younger generation, all the girls.
