Kim Kardashian (along with Tyga, Blac Chyna, her sis Kourtney, Naya Rivera and more) traveled to Las Vegas alongside her fiancé Kanye West on Friday night, to catch his Yeezus tour stop there and celebrate her 33rd birthday. During the show, a proud Yeezy shouted out his fiancée in the crowd, before launching into his love song of sorts, “Bound 2.” So cute! Check out the footage below.
