Mel B started out the night completely unrecognizable at a party in London to fête the launch of Glaceau Vitamin Water's XXX Triple Berry drink.

Maybe the former Spice Girl delved into her Halloween wig drawer a little early (or perhaps she borrowed a look from ATL Real Housewife Kim Zolciak's wig line), but turns out the light locks were just the beginning.

Donning a flapper-like beaded dress upon arrival, it seems the hard-bodied singer just couldn't decide what to wear. So, in true diva fashion, she underwent three wardrobe changes.

And in the same non-committal fashion, Mel apparently decided that blondes don't have more fun and went back to more natural, long brunette tresses and a relatively conservative red minidress, before changing yet again that is!

And, in our opinion, third time was not a charm. The final frock, a long black gown with cleavage out to there, which she chose for the premiere of Michael Jackson's "This Is It!," just didn't do it for us.

It seems the only thing that remained consistent through the night was the mother of two's blinged out wedding ring, gleaming watch and hubby arm candy.

So, while we definitely know which look we consider most "Posh" and which most "Scary," we want to know what you think.

Tell us your favorite of Mel B's three dresses. And should she consider going blonde for real? Leave a comment below!
