Gwen StefaniGwen StefaniThere could only be one Gwen Stefani - fact.

However, we have met her match in the facial dept.

Let us introduce Gwen's twin.

And would you believe it, she's a celeb too, but she isn't a warbler.

The lady in question is Playmate, Holly Madison and looking at their two chops it's easy to see the similarity.

It's purely by chance, however, as the two of them share no DNA.

Yet they obviously share a love of the bleach.

But in the small gene pool that is Celebville, there are more than a few deadringers knocking around.

Check out all the starry doppelgangers in our gallery of celebrity lookalikes.
