First, the man, then, the manicure.

In a sea of celebrities, Gigi Hadid stood out not only for her look, but for her arm candy. On Monday, the Victoria's Secret model and her boyfriend Zayn Malik made their first official red carpet debut as a couple at the Met Gala in New York.

Gigi and the former One Direction singer's relationship hasn't exactly been a secret, as they participated in a steamy photo shoot together for Vogue in April and he helped her ring in her 21st birthday in Los Angeles and Las Vegas recently.

None of those things quite say "we're a couple" like a hand-in-hand red carpet appearance.

And really, Zayn, one of many celebrities trolled by the Internet for his interesting gala outfit, may have been holding the most expensive hand in the room. Gigi accented her metallic Tommy Hilfiger gown with sharp-edged fingernails made of pure chrome.

Refinery 29 reported that the couture manicure included a cluster of crystals on the underside of each nail, as well. The custom talons were made by celebrity manicurist Mar y Soul in conjunction with Kiss Products, who proudly showed of Gigi's look on Instagram.

The cost of the manicure: a cool $2,000.

Interestingly, Gigi's digits and the extensive details of them went somewhat unnoticed in all the Met Gala. It also could have been due to the fact that she and and her boyfriend of six months posed on a red carpet for the first time together.

But, it doesn't seem like the couple will be making a habit of willingly being pictured together at events.

In March, Zayn told Complex magazine that he tries to keep his love life private and separate from his professional life.

"I try to keep the two very separate. I try to, as much as I can," he insists. "But there's only so much you can do. It's just one of those things now, in the background. I just leave it as a bit of a noise in the background."
