I'm usually unimpressed with celebrity publicity stunts attempting to garner attention. Or the flip side: celebs that believe their image is such a hotcommodity, not even $150 for a concert ticket gets you visual access to their face (yes you, Kanye).
And then there's stars like Emma Stone. She's not a fan of the attention, but is willing to direct it to causes that really matter. Loved reading about her response to the paparazzi . When her and Andrew Garfield were hounded, they took the opportunity - holding signs in front of their faces that listed various charities they supported.
