Kevin Mazur/Getty The singer continued her somewhat toned-down streak for the 2019 American Music Awards, going with a dramatic eye paired with nude lips and cheeks. 05 of 20 2017 Emma McIntyre/AMA2017/Getty No makeup, no problem. The singer stepped out in November at the American Music Awards wearing barely any makeup, and most recently, posed on the cover of Paper Magazine flaunting her freckles. "I'm at the place, even musically, where it's a liberating feeling to be able to strip it all back and appreciate who you are and your raw beauty," she said. 06 of 20 2016 Before embracing a more toned-down look, Aguilera debuted some of her most daring beauty looks — like this purple hairstyle — when she was a judge on The Voice. 07 of 20 2014 Steve Jennings/Getty One look she'll never let go of: classic, Old Hollywood-style side-swept hair paired with a bold red lip and tons of lashes, which she rocked often during her Moulin Rouge era. 08 of 20 2016 Kevin Winter/Getty During one of her many hair changes in 2016, Aguilera swapped her blonde hair for a bold shade of auburn, a hue she complemented with a red lip to perform at the "Hillary Clinton: She's With Us" concert. 09 of 20 2012 Trae Patton/NBC/NBCU Photo Bank via Getty Images Bright colors have never been out of the star's reach -- like the time she matched her hot pink highlights to her pink lips on The Voice. 10 of 20 2011 Jason Merritt/Getty No matter how far she takes her looks, she'll always revert back to a classic look. 11 of 20 2010 Getty A short, chin-length golden blonde bob made its way into her ever-changing hairstyle rotation, marking one of her most drastic cuts to date. 12 of 20 2008 Jon Kopaloff/FilmMagic Records weren't the only thing she took platinum: 2008 marked Aguilera's year of bright blonde hair and blunt bangs. 13 of 20 2008 Kevin Winter/Getty Sticking with her white-blonde hue, the pop icon paired her ringlets with even shorter, choppy fringe. 14 of 20 2004 Mike Blake/Landov To take home a Grammy award for Best Female Pop Vocalist for "Beautiful" in 2004, Christina sported black flapper-style finger waves and a magenta lip. 15 of 20 2003 Getty The singer loved black eye liner so much by 2003 that she dyed her hair to match. 16 of 20 2001 Steve Granitz/WireImage In 2001, a blonde braid-accented, voluminous 'do was basically a "casual" look for Aguilera. 17 of 20 2001 Steve Granitz/WireImage Her "Dirrty" braid phase lasted almost a year.
