Bronny James is one step closer to becoming a college basketball star -- he just inked his letter of intent with USC ... and the occasion was so momentous, LeBron James said he shed a tear!!
Poppa James posted all about the Proud Dad moment on his Instagram page Thursday morning ... writing that he was "so damn happy" to see his 18-year-old boy put the pen to SC paper, locking him in to the Trojans for at least the 2023-24 season.
"Pops shed a gangsta ud83eudd7aud83dude22 seeing this," LeBron wrote.
