And correct us if we're wrong, but we bet it's one of the finest YOU'LL have seen for a while, too.
We're not wrong, are we?...
Christina recently returned to her position of mentor on NBC's The Voice Season 10 after alternating with Gwen Stefani for the last few years. She makes up a stellar team along with Gwen's beau Blake Shelton, Adam Levine and Pharrell Williams.
And like Gwen, she never fails to give us plenty of fabulous hair (and red lip!) inspiration on the show.
"Last night's look for the battles," Christina Instagrammed on Tuesday (15 March) along with the gorgeous snap (above) of her hair and make-up from Monday night's appearance.
As we're sure you're aware, we love a topknot here at Reveal HQ, but this one definitely tops our list of lust-after looks so far this year.
With a slightly messy, arched bun and a twisted section of hair pulled back from the front, this had to be the topknot of all topknots. Sorry Kendall Jenner, Kaley Cuoco and Ashley James, but you've been totally out-topknotted!
To copy Christina's look, first section off the front of your hair (about the width of your eyes), and clip this to one side.
Next, scrape the rest of your hair up into a high ponytail at the crown of your head and secure with a band. Twist or loop the ponytail around your finger – depending on how long your hair is – then grip it to the base using plenty of grips. You could also use another hairband if that works better for your hair length.
To finish, slick the front section over to one side of your bun, then twist it around the bun and pin into place.
Fix with hairspray. The end.
