For the first time in months, Taylor Swift wasn’t the most talked-about musician at a Kansas City Chiefs game. At halftime, the Super Bowl transformed into an epic 13-minute Usher concert in which he wowed viewers with a medley of hits, incredible choreography, a temporary lack of a shirt, and fabulous cameos by musicians he’s collaborated with, like Ludacris, Lil Jon, and Alicia Keys. And while Keys’s sparkle was impossible to ignore, you might have missed out on one of the most glamorous aspects of her look: her nails.

Keys was absolutely glowing as the cameras rolled on her at the most stunningly sculpted red piano. True to her usual aesthetic, Keys’s makeup was fresh and light, and she wore her hair in long, thick twists. Her corsetted Dolce & Gabbana catsuit matched her piano and was covered in crystals and sequins. But even if you were paying rapt attention to the performance, there’s a decent chance you didn’t notice that Keys’s manicure is just as glamorous as her ensemble.

Manicurist Dawn Sterling shared a video closeup of the manicure masterpiece she crafted for Keys. “Ruby red crystals for THE BIGGEST,” she wrote on the clip. The short, squared-off nails started with a sheer, pink base, on which she added oval, ruby-like gems completed surrounded by diamond-like crystals. Sterling also framed the baubles with a red, French-like tip.
