Rapper Snoop Dogg helped funnyman Will Ferrell and the cast of Old School unwind after a long day on set by lighting up and getting high with his comedy co-stars.

The hip-hop legend made a cameo in the 2003 film, starring alongside Ferrell, Vince Vaughn and Luke Wilson, and the longtime marijuana advocate reveals they all joined him for a smoking session after production wrapped.

During an online chat with fans on Reddit.com on Tuesday (02Jul13), Snoop revealed he smoked with "Vince n the rest of tha crew (sic)" but there was still one famous pal he had yet to light up with - "My uncle Willie Nelson".
