Hey, at least this is the good kind of addiction! Our favorite rehabber Lindsay Lohan has been spotted multiple times with Ariva, a nicotine substitute (in the form of a hard lozenge!) to help people quit smoking... and it's no coincidence reports The Sun. The Mean Girls star is endorsing the product - "holding the packet of special gum in view of the paparazzi," says The Sydney Morning Herald - as part of a deal with Aussie playboy Andy Valmorbida.

Trying to get smokers - including herself - to quit? Now that's a good cause to get behind!
