The topknot, the lazy girl's go-to style, made many chic appearances at the 2015 American Music Awards on Nov. 22. Fashion It girl and reality star Kendall Jenner rocked one [1] on the red carpet, as did BFFs Christina Milian and Karrueche Tran, but the most notable topknot of the night was that on none other than Latina superstar (and AMAs host [2]) Jennifer Lopez [3].

Though she made many hair, makeup, and wardrobe changes [4] throughout the night, J Lo's classic updo truly stood out — especially when paired with that sparkly red ombré dress. If you're curious about how she achieved such a perfect bun (there isn't a hair out of place), we have the supereasy how-to straight from her hairstylist Lorenzo Martin for L'Oréal Paris.

Lorenzo first gathered J Lo's hair into a high ponytail, then he twisted the hair around its base, securing the bun with bobby pins. He finished off the stylish look with a spritz of Elnett Strong-Hold Hair Spray [5] ($15) and — this is the key to that perfect style — a bit of Advanced Hairstyle Lock It Extreme Style Gel [6] ($4) to keep it all in place. Keep scrolling to see more pictures of the final look and some of the rival topknots of the evening, and then check out all of J Lo's best hosting moments [7].
