Like this legendary Tatler girl, the Three, a triumvirate of fashion models who have elegantly gatecrashed the conceptual art-world party, don't actually "do" anything. They don't paint, they don't sculpt, they don't draw, film or photograph. They just "are". You think Martin Creed's Turner Prize effort with the light turning on and off is silly? Or perhaps you still regard Tracey Emin's unmade bed as the apotheosis of over-hyped conceptual art lunacy? Well, brace yourselves, conceptualist fans, because this is where it gets even sillier.
