Gwen Stefani wears a brown braided wig and goes for a bloody cowgirl look as she heads inside the 2015 Casamigos Tequila Halloween Party on Friday night (October 30) in Beverly Hills, Calif.

Gwen was also joined by fellow The Voice judge Blake Shelton who was pretty disguised in a poncho and fake beard.

Later, Gwen took to her Instagram to share a selfie in her costume.
