LeBron James' second-oldest son is celebrating his Sweet Sixteen on Wednesday ... and the Los Angeles Lakers superstar made sure to wish Bryce a happy birthday with a special shout-out to the teen hooper.
"SCREAMING HAPPY 16th BIRTHDAY 🗣️🗣️🗣️🗣️🗣️🗣️🗣️🗣️ to my Twin MAXIMUS @_justbryce!!!!!!" Bron said on Instagram. "I LOVE YOU YOUNG 🤴🏾!!!"
"Keep going up and up and up! Love the young man you are and becoming every single day!! 🙏🏾🤎🤎🤎🤎🤎🤎👑."
LeBron's tribute also came with several recent pics of Bryce ... showing him balling out on the court and enjoying some downtime as well.
LBJ's oldest kid, Bronny, just graduated from Sierra Canyon High School and will attend USC in the fall ... and Bryce is slated to suit up for Campbell Hall for his remaining two years before college -- so yeah, we're all officially old.
The bday also means there could be another member of the James Gang on the road ... and if Bryce is getting his license, we're sure he'll be riding around in style.
No word on what the plans are to celebrate -- but Bronny had Travis Scott perform at his bash last year, so the sky's the limit!!
