TMZ reports that Post Malone's pal Rich Chigga came through like a true homie should. After feeling like Post needed to get hype before his upcoming Rolling Loud set, Rich ordered a song request from a top-tier (shout-out to Yelp) mariachi band. 

Apparently, Rich met with the band and hooked them up with the lyrics to "Congratulations." The band practiced before being dropped off at the venue, where they were all set to perform. The whole ordeal was originally set to cost Rich $350 for a couple of hours, but Post showed up late as hell, which ultimately ran up the cost to almost $1K - all of which came out of Rich Chigga's pocket. 

It was probably worth it, as the clip has since gone viral. Plus, look how happy everybody looks.
