It's easy to forget that Christina Aguilera wasn't always synonymous with a signature red lip and platinum retro waves. Back in her "Dirrty" days, the beauty chameleon constantly experimented with edgy looks and hair 'dos ranging from tiny rainbow braids to jet-black tresses.
Since 2004, however, the "Beautiful" songstress has primarily stuck to her trademark blonde with subtle variations.
Xtina's newest red-hot look, then, is one of the biggest recent beauty game-changers for the big-voiced songstress. She debuted a brand-new red shade for a performance at a Hillary Clinton fundraiser Monday night in Los Angeles, and the 35-year-old has never looked better.
The chart-topper wore her auburn hair in retro waves and accentuated the color with crimson lipstick and a plunging black suit as she performed her biggest hits at the Greek Theatre.
The Voice coach also took to Instagram to share a more close-up shot of the sultry look with her fans.
No word yet on whether this auburn look is here to stay, but we're definitely liking the change! See more celebrity hair makeovers in our gallery.
