Snoop Dogg and Wiz Khalifa graced 'Late Night With Jimmy Fallon' with their presence last night, performing 'Young, Wild & Free,' the single from the soundtrack to their new movie, 'Mac & Devin Go to High School.'

The lanky rappers wore stylish winter hats as they rapped the song, which debuted in the Top 10 in October, and urged the late-night audience to "Roll one, smoke one, when you live like this you're supposed to party." Featured artist Bruno Mars was absent, but Fallon's house band the Roots were more than capable of picking up the slack.

Wiz took promotion to a new level, hyping the film during the song itself, while Snoop actually sang the hook about getting drunk and smoking weed. The Snoop-Wiz collaborative soundtrack, which also features Mike Posner, drops next Tuesday, Dec. 13.

After their Fallon performance, the rappers spent the evening performing at New York City's Terminal 5 as part of their brief joint tour.
