Rich Chigga overcame visa issues to make it in time to perform at Miami's Rolling Loud festival over the weekend. The lasting image of his trip to Miami will not be his performance, but his backstage "Congratulations" sing-a-long with Post Malone and a mariachi band. 

It's unclear if Rich Chigga actually knows the words to "Congratulations," which was recently certified platinum, but he is nearly as enthusiastic as Post Malone, who smiles broadly as he sings and holds his customary beer and cigarette. Video of the sing-a-long has garnered 185 thousand retweets (and counting) on @JuncajJon's Twitter account. Watch below.
