Leave it to Lady Gaga to do the unexpected. While in London, the normally blond singer stepped out with a whole head of purple hair, accessorized with a purple-toned lipstick and a matching teacup and saucer. Does it make you grin or... grimace? (Heh.) Since you liked my pretty in pink slideshow so much, I thought I'd pay tribute to Gaga's new hue. Check out all of these purple people now.
