Gwen Stefani unwraps hot new promo pic...

Gwen Stefani mania is upon us! 

Today, she officially debuted her brand new single 'Baby Don't Lie' on VEVO, previewed another new track called ‘Spark The Fire’ featuring Pharrell and now drops a spanking hot new promo pic (courtesy of photographer Daniel Sannwald). Gwen will preview the Sophie Muller/Weirdcore-directed video for 'Baby Don't Lie' later tonight.

She will preview the clip on The Voice (NBC, 8PM ET/PT), and the video will premiere in its entirety on VEVO tomorrow.
