Nelly belted out several home runs ... on a stage in Los Angeles as the co-host and performer for his carnival-themed MLB All-Star after-party with Dodgers star Mookie Betts.
The Diamond-certified rapper brought Betts and his wife Brianna up on stage, dedicating his “Hot In Herre” performance to them … just like he did a few months prior at their wedding!!!
Mookie and Nelly have become fast friends since that big day back in December, and collaborated on Tuesday night's event to celebrate the All-Star Game .
