As we previously freaked out about reported, Gwen Stefani has collaborated with OPI to create a totally rockin' line of nail polishes. And, happily, the polishes are just as cool as promised. All of the colors are rad, but once we saw the Push and Shove Duet Kit, we knew we had to take it for a spin in the Beauty Test Lab.

Push and Shove looks like your typical silver polish in the bottle, but it claims that when you apply it over the included Lay Down That Base basecoat, the polish dries to a super-cool mirrored-chrome finish. Needless to say, we were intrigued. (Who doesn't like shiny things? Answer: No one.)

So, tune in to see if Gwen's new set lives up to its promise. Now, If she could only launch a full "Look Exactly Like Gwen Stefani Kit"...then we'd really be talking.

OPI Gwen Stefani Push And Shove Duet Set, $9, available at Ulta.
