Kanye West and Justin Bieber were among the many famous faces performing at 102.7 KIIS FM's Wango Tango concert in Carson, California on Saturday, and the boys tore up the stage! Too bad they didn't do a set together...

Though Yeezy's wife Kim was on a plane to Brazil, the rapper was supported by his mother-in-law Kris Jenner and sister-in-law Kendall Jenner. As far as we're concerned, that's a better deal! But the big deal of the day was when the Biebs performed and revealed that he will be doing some touring this summer!

Though Bieber has made a few surprise appearances at small shows and with Ariana Grande, his last big tour date was in December of 2013. Between then and now he managed to get into quite a bit of trouble, so getting back on the road might be good for him! After the show, Biebs tweeted, "Good to be back," and manager Scooter Braun posted an Instagram photo of Biebs' performance on Saturday nigh and wrote, "Great to see him back on stage. @justinbieber puts on a show! #wangotango."

We wanna know more about Justin's shows this summer though!
