Christina Aguilera made an appearance for "The Voice" in Calif. Sunday, debuting a new look with her hair: vibrant purple ombre streaks.

Part of NBC Universal's "The Voice" press junket and cocktail reception in Los Angeles, the 31-year-old mother-of-one showed off her new hair for the appearance with co-stars Adam Levine, Blake Shelton, Cee Lo Green, Christina Milian and Carson Daly at executive producer Mark Burnett's home.

Aguilera showed off her signature platinum blonde hair with violet ombre streaks. The highlights vary in color, some a lighter shade of lavender and others with a hint of magenta. The starlet paired her new hair with matching purple eye shadow, black leggings, a black-and-white tribal printed dress, a leather jacket and Christian Louboutin heels.

Meanwhile, the singer is prepping to release her new album and will debut her new song "Your Body" during "The Voice" premiere in Sept. on NBC.

Aguilera isn't the only one sporting the colorful ombre hair trend. Back in January, Selena Gomez sported long extensions with a blonde ombre look. By mid-June, the Disney starlet had transitioned away from the ombre and instead donned a rocker 'do with electric blue and purple streaks.

Here are photos of some other stars rocking the ombre and/or colorful streaks trend.
