cdertainly it is Cameron Diaz! she is off the scale on all star hotness charts!

for serious its probably canis major the biggest known red giant star-but its frigid in comparison to Cameron Diaz!

you should of phrased your question correctly by asking who instead of what!! Cameron may be hotter than any known person alive but she is a human being, not an object!!...Show more
