If Rob Kardashian's family doesn't want to congratulate him on locking down Blac Chyna ... it's all good, 'cause the DJ at his fave strip club's got it handled.
The DJ at Ace of Diamonds strip club shouted out the newly engaged couple on Monday night. Our sources say someone on Chyna's team whispered in the DJ's ear ... and he decided to share with the club.
Check out the crowd's reaction, and how Blac Chyna put her rock on display.
Btw ... still waiting for anyone related to Rob to say a single word.
