The pair had court-side seats as they watched the Los Angeles Lakers face off against the Los Angeles Clippers for an afternoon game that ended with the Lakers beating their hometown rivals 112 to 103.
Blue -- who rocked a denim jacket, black pants and shirt with black combat boots -- took in the whole game with her megastar dad, who sported a grey sweater, and a ball cap. Her mom, Beyoncé, wasn't in attendance.
After the game, the proud dad introduced Blue to a few of the players, including JaVale McGee and Anthony Davis.
The rapper's daughter politely shook hands with her dad's famous friends on the court, after the win.
She also got a chance to meet LeBron James, and the young girl appeared to get a bit bashful while talking with the superstar, who promised to get her a signed basketball, according to a video recorded by ESPN.
Despite her own superstar parents, getting to meet the NBA legend still seemed to leave Blue in awe.
