Christina Aguilera Has Red Hair Now, And It Looks Phenomenal

"What a Girl Wants" is to swoon over Christina Aguilera's latest hairstyle.

The singer and "The Voice" judge debuted a red, flowy 'do Monday night, looking nearly unrecognizable and absolutely gorgeous. 

The look, complete with a bold red lip and sultry eye makeup to go with it, totally channeled Jessica Rabbit: 

But we have to admit we're getting some serious "The Little Mermaid" vibes, too: 

Aguilera has made a habit of ditching her signature blonde hair over the years. There was a dark brown look, pink braids , and who can forget the red she had in those fateful "Come on Over" days?

Still, this new look -- with its old Hollywood glamour and vibrant, bold color -- might just be our favorite yet. 

Get it, X-Tina!
