Tuesday's episode of Late Night With Jimmy Fallon was action packed with guests Justin Bieber and Los Angeles indie rockers Local Natives. My Morning Jacket's Jim James, who performed on the show Monday night, even joined house band the Roots. Watch above.

The highlights: Bieber (at 16:50 mark) discussed his new acoustic album and world tour, his upcoming hosting stint on Saturday Night Live, hanging out with his friends Lil Za and Lil Twist and why he's always getting stopped by the police (it's due to his white Ferrari, he says). 

The best part, though, came during a three-point shoot out with Fallon, when Bieber made out with a mannequin that looked suspiciously like, well, Justin Bieber.
