JUSTIN'S A N*E*R*D!
The star makes his second appearance in a week with his pals....
In a repeat of the group’s Edinburgh gig that followed the
MTV Europe Music Awards last week, Timberlake performed guest vocals for almost the entire set at London Brixton Academy.
One fan at the gig told NME.COM: "The place went wild when he came on stage. Girls were trying to get up on the stage to dance with him during the performance."
