Russell Westbrook is staying with the Lakers ... and is sending a message to all the haters who don't like it by posting a video of him absolutely rockin' out to Beyonce's "Break My Soul."
The 9-time NBA All-Star shared the clip of himself jammin' to Bey's new song on social media on Tuesday ... just a few minutes before ESPN's Adrian Wojnarowski broke the news that Russ will exercise his $47.1 million option to stay in L.A. next season.
The clip is hilarious .
