Kylie Jenner Rocks a Diamond Grill and Pink Hair on Tyga's Instagram

The reality TV star is taking her accessory game to a whole new level.

Kylie Jenner's taking a style cue from Tyga!

The 18-year-old reality TV star copied her boyfriend's look, sporting a black beanie and a diamond grill in a photo posted to his Instagram on Tuesday.

"Augghhh," the 25-year-old rapper, who frequently rocks the accessories, captioned the pic.

In contrast to the badass grill, we couldn't help but notice Kylie's sweet bubblegum pink locks, which she's been flaunting since Valentine's Day. Kylie debuted the bright-colored wig on the romantic holiday in a series of snaps, including one of her and Tyga posing in front of a helicopter.

While Tyga's in Los Angeles filming season two of his MTV reality show, Kingin' With Tyga, his girlfriend's been showing off her pastel pink hair in New York City.

Before heading to the Vera Wang Fall 2016 runway show at New York Fashion Week, Kylie took to social media on Tuesday, posting a photo of her modeling a sparkly gold dress by the designer, which she styled with black leather knee-high boots.

Her pout matched her hair color perfectly, and she let her 51.5 million followers know that the Candy liner and Koko Matte Liquid Lip shade she was sporting were, of course, from her latest Kylie Cosmetics collection.

Kylie isn't the only one in the Kardashian-Jenner crew making headlines for their hair, however. Just last week, Kim Kardashian rocked a platinum blonde 'do while supporting her husband, Kanye West, at his Yeezy Season 3 fashion show and album release party at Madison Square Garden.
