WATCH: Justin Bieber and Tyga Did a Thing at 1OAK Nightclub

Collaborations!

Justin Bieber and Tyga turned up the club in tandem on Sunday night (Jan. 31) when they gave a surprise performance at L.A.’s 1OAK nightclub. Kourtney Kardashian’s rumored chew toy and Kylie Jenner’s bae-in-the-doghouse performed “Sorry”, “What Do You Mean”, and their 2013 collaboration “Wait For a Minute“.

Bieber proclaimed to his fans mid-set atop of the DJ booth, “If you’re not feeling this right now, get the f**k out of here.”

But his harshness was forgiven because he gave the ~ladiez~ roses.
