Ke$ha and Rihanna were on the same venue, at the UK’s T in the Park festival, and both flashed the audience in one of the grossest displays of pornographic nastiness ever recorded. In the skin-trade, these body positions are money-shots: centerfolds of spread-eagled girls - pioneered by the then raunchy Penthouse magazine back in the 1970s. At the time, Playboy never stooped that low; their girls by no means opened up and displayed their charms in front of the camera. In 2013, they do it on stage. Welcome to the new normal.
