Justin Bieber had a few surprises in store for fans at Coachella weekend 2! On Saturday night, the Peaches singer returned to the desert in Indio, California to serenade festival goers once again - but this time with some help! While the Biebs mostly stuck to the same type of laid-back performance he offered during weekend 1, which included surfing his old music videos and performances on YouTube live in front of the audience, he definitely raised the energy this time around with help from some familiar faces.
