Will and Jaden Smith may star together in their upcoming sci-fi flick After Earth, which they’ve been promoting like craaaazy, but it's music we're interested in today. We’re putting them against each other for a late night rap battle!
Will stopped by The Late Show With David Letterman while his 14-year-old son hung out at Late Night With Jimmy Fallon last night. Sure, they both talked about their movies and other miscellaneous topics, but one thing also went down for the father and son –- they both rapped on the shows!
Check out both of their performances after the jump.
