Post Malone was at a bar in Houston on Christmas Eve when he met a bartender named Renee Brown.
Renee, who works two jobs and is a single mom, received an extra special surprise before he left...a $20,000 tip.
This was the first time Renee said she’s had to work on Christmas Eve - a day she usually spends with her daughter.
And she ended up with a Christmas miracle...
