As well as rocking Liverpool this week, Madonna invited Britney Spears up on stage to perform during the Los Angeles leg of her Sticky and Sweet tour. The singers had almost the exact same shade of blonde hair, but with Madonna working the undulating curls trend, while Britney went for sleek and sophisticated. Britney opted for smoky eyes with an orangey pink shade of lipstick. Meanwhile Madonna sported pale grey and lilac eye makeup and a softer shade of lip colour to suit her porcelain complexion. Whose beauty look do you prefer?
