It's amazing what a difference a bottle of hair dye can make, isn't it. We literally had to stare at this photo for a good few minutes until we worked out who it was – and we still can't quite believe the transformation. Strictly Come Dancing's Kristina Rihanoff donned a dark wig and even darker tan in this picture for tanning professionals St Tropez – and we think she looks really nice. In fact, we think we actually prefer the dark bob to her usual blonde curls. Kristina's hair has become the one thing that makes her instantly recognisable on the Strictly dance floor, so we can see why she keeps it. Still, must be nice to know you can transform into a sexy, Christina Aguilera-alike with the simple application of a wig, eh? Do you think Kristina looks better as a blonde or a brunette? Vote below.
Guess who this is...
