As the night ended, the “Congratulations” artist took it upon himself to spread some holiday cheer by way of a $20,000 tip left for a single mother working at the bar. The woman in question was identified as Renee Brown, a 36-year-old single mom who works two jobs, loves her kid, and never stops, à la Reba McEntire.

"This definitely wasn't the Christmas Eve I was expecting, but one I'm forever thankful to have had," Renee Brown, the bartender and single mother said.

Post Malone made a bartender's night at The Railyard bar in Houston on Christmas Eve when he tipped her $20,000, she told Music Mayhem in a new interview.
