Last night, Kanye West hit up Justin Bieber's Purpose World Tour during its second night at Los Angeles' Staples Center. At the show, Kanye kicked back with his wife, Kim Kardashian, who was rocking a very cool Life of Pablo jacket. The two waved to fans from their prime seats and sat back as Bieber ripped through his stream of Purpose hits. Of course, Kanye had to stand up when Bieber performed "What Do You Mean?" which 'Ye recently confirmed as his favorite track of 2015. He bobbed his head and danced like the old Kanye as he showed that not even Yeezus can resist the fire that is that song. Kim also serenaded her husband to Bieber's "As Long As You Love Me" during the show. Thankfully, she also caught everything going down on her Snapchat.

Bieber even thanked Kanye for coming to his show on Twitter. "Shout out to one of my inspirations @kanyewest for coming to the show tonight. Had to go big. #PurposeTourLosAngeles night 2." The two actually nearly collaborated before when Bieber freestyled on "Ultralight Beam," although his cut unfortunately didn't make the final version. This isn't the first huge sighting at Bieber concert, either. The night before, Chance the Rapper and Big Sean both showed up at Bieber's concert. Huge squad envy.
