Giveon had royalty present during his concert in L.A. on Monday ... 'cause the R&B singer brought out Lakers superstar LeBron James in the middle of his show!!
LeBron -- who was enjoying the Lakers' day off -- made a special guest appearance at the L.A. Live concert ... and judging from the reaction of the crowd, everyone was pumped.
The "Heartbreak Anniversary" crooner had to playfully persuade King James to come out and address the crowd ... chanting "LeBron, LeBron. LeBron," before the 4-time champ strolled out on stage.
"Make some noise for LeBron, please," Giveon said.
The entire interaction was dope ... as Bron -- who routinely shows love for his favorite musical artists -- embraced the songwriter in front of the packed crowd.
Of course, LBJ made sure to return the favor by giving a shoutout on his Instagram saying, "A star flat out. My brother @Giveon love my brother."
"Thank you to the GOAT @kingjames for coming out ... my brother 4L," Giveon replied.
If you listen closely enough, you can even hear chants of "MVP" from some of the concertgoers in the building.
And, judging from his latest string of performances, it's not hard to see why fans would be moved to shower LBJ with such high praise.
LeBron and co. -- winners of their last two games -- look to keep the momentum rolling Tuesday ... as they take on the Sacramento Kings.
