Gwen Stefani Feat. Eve

Dr. Dre's production is firm and spacious, with Mike Elizondo and Mark Batson contributing to the instrumental setting and writing. The rhythm has enough weight to hold the song together while the lead melody takes a much more exaggerated, almost stage-like route across it.

Stefani makes that theatricality part of the fun. The voice bends around the tune with a recognisable combination of sweetness and edge. Eve's verse then changes the scale of the performance, bringing clearer rhythmic punctuation and a more grounded confidence into the same imagined world.

The collaboration does not depend on the two singers sounding alike. Its most effective passages let their differences remain obvious. A melodic line that might feel overly decorative on its own becomes more agile when another voice answers with a different pace and attitude.

The writing credits include Jerry Bock and Sheldon Harnick alongside the contemporary songwriters, reflecting the melody's wider musical ancestry. The finished recording is unmistakably part of Stefani's first solo album world: bright references, a strong visual imagination and enough rhythmic discipline to keep the dressing-up attached to a real pop groove.
