Bryce James had his Senior Night on Thursday, and with the Lakers on an off day -- both LeBron and Bronny made it out to celebrate!
The two L.A. stars -- wearing matching sweatshirts -- drove to Sierra Canyon H.S. to watch Bryce's final home game ... and they were joined by Savannah and little Zhuri too.
They all had some sweet seats for the affair -- sitting right on the court -- and they even got to take some pics with Bryce before his tilt to commemorate the special night.
