Lady Gaga

This one is a no-brainer. It's often impossible to understand what message this perpetually-shocking fame monger is up to. Is she attempting to patronize art, make a statement against oppression or just shock her way into fame?

Her career has already been punctuated with her outlandish sartorial choices. And when she isn't draping herself with meat or wearing some seriously kinky bubble bath costumes, she's definitely spreading rumours about her own bisexuality or suing ice-cream parlors for debuting new flavors like 'Baby Gaga'—which has breast milk as one of its ingredients.
