The America's Got Talent judge spruced up her talons with a sophisticated black base and statement metallic detailing.
And if you want to steal her look, there's no need to get creative with the nail art pen.
Heidi's talons actually came courtesy of easy-peasy nail wraps - the OPI Pure Lacquer Nail Apps in Metallic Wave, £21.50 for a set from QVC.
Nail wraps are great because they provide gorgeous, foolproof designs with zero drying time. Plus these ones are actually made from real nail lacquer. Pretty cool, huh?
Heidi accessorised her stand-out mani with bold chunky rings and a sleek monochrome clutch.
She's one stylish lady!
