'American Boy' singer, Estelle, showed up to Avalon in Hollywood rocking her twinkle toe status in blue Christian Louboutin pumps. Mmm.. Loves them! I guess Dorothy isn't the only one who has glitter slippers. Estelle, along with Usher, Letoya Luckett and many others, were there to celebrate the launch of Belvedere Vodka's newest product, Belvedere Red. Looking great Estelle! If you keep working it like this.. you'll find your American boy in no time!
