Earlier this month, John Mayer had publicly tweeted about recently discovering Post Malone’s music and how much he liked it. Posty replied to him with “you’re f*cking great dad.”

John Mayer had a show at The Forum in Inglewood, California on Sunday (July 30) where he brought out Post as a special guest to perform his hit ‘Congratulations’ in front of a sold out audience. The Quavo-featured song is already platinum, having peaked at #8 on the Billboard Hot 100 and currently holding the #12 spot.
Malone and Mayer rocked out the song together with their guitars while legendary drummer Tommy Lee did the drumming duties. Watch the epic footage below (via rap-up):
