The regular collaborators performed a fun-filled duet on the show this week to celebrate it's 10-year anniversary.
Pharrell Williams made a surprise appearance on The Voice US this week to give an incredible duet performance alongside Gwen Stefani.
The No Doubt front woman stopped by the talent show to perform her 2004 classic hit 'Hollaback Girl', produced by Pharrell himself, before the 'Happy' star showed up halfway through to finish off the duet.
The US star then went on to perform his track 'Come Get It Bae' from recently released album 'G I R L' as part of his appearance on the show.
'Hollaback Girl' was originally released ten years ago and featured on Gwen's solo album 'The Sweet Escape'.
