Jennie's custom 'blue rose' grillz draw mixed reactions: "Looks like a cavity" vs. "fashion icon"

Blackpink's Jennie has sparked an unexpected online debate over a unique piece of "grillz" tooth jewelry worn during her performance at a major US music festival, where she also debuted a brand-new song.

On June 7 (local time), Jennie took the stage as the final headliner at 'The Governors Ball Music Festival 2026' held in New York. Delivering an explosive 60-minute performance, Jennie treated the crowd to a 17-song setlist, kicking off with "Filter" and performing hits like "Damn Right," "Mantra," and "Like JENNIE." She particularly drove local fans wild by giving a surprise premier performance of an unreleased new track.

However, immediately following the concert, social media platforms and online communities became just as hyper-focused on Jennie's teeth as they were on her music.

Jennie appeared on stage sporting custom grillz featuring a distinct blue rose design. The shimmering tooth ornament caught the stage lights, creating an intense visual presence. The piece was revealed to be crafted by Mark Cruz, a private jeweler based in Los Angeles.

Taking to social media, Mark Cruz introduced the piece, writing, "Created a new piece with Jennie for her Governors Ball stage. It's a completely custom 14K white gold piece handset with VVS1 diamonds and blue rose enamel detailing." The blue rose holds special significance for fans, as it is known to be Jennie’s favorite flower.

Public reaction online, however, was starkly divided. Some fans praised the look, commenting, "Since Jennie wore it, it’s going to become a trend again," "The blue rose detailing is so beautiful," "The pinnacle of hip styling," and "As expected of a fashion icon."

Conversely, other netizens expressed hesitation, with comments like, "From a distance, it looks like a cavity," "I genuinely thought her tooth was decaying," "It looks pretty up close, but it’s a bit much from afar," and "She only pulls it off because she is Jennie."

In various online communities, users debated the look, writing, "I thought it was a tooth gem at first, but I was shocked because it looked like tooth decay," and "It’s definitely hip, but it’s bound to divide opinions."

Following her successful headlining set at 'The Governors Ball 2026,' Jennie is slated to continue her global festival run with scheduled appearances at the Roskilde Festival in Denmark, Open'er Festival in Poland, Mad Cool Festival in Spain, Lollapalooza Chicago in the US, and Summer Sonic 2026 in Japan.
