Congratulations, fellas. Our little cheerleader is all grown-up and able to purchase cigarettes and pornography. She was greeted by a gaggle of photographers at LAX on her 18th birthday after returning from a stint on David Letterman on the east coast. The paparazzi happily reminded Hayden that she was now able to legally get her hands on tobacco products. To that, Hayden replied that she could also buy porn and everyone thought it was all so hilarious. But will we still be laughing when she’s in rehab three months from now in an attempt to treat her newly-developed porno and chewing tobacco addictions? Time will only tell.
