Drake's been doing more than just wining and dining his new boo, Johanna Leia, at Dodger Stadium ... he's also been mentoring her basketball prodigy son for months.
Sources close to the pair tell us they first met months ago through high school basketball -- Johanna's son, Amari Bailey, is a top prospect -- and the relationship grew from there. We're told Drake and Amari hit it off, and Drake's offered the kid advice on finances, fame and life, in general.
Amari is headed to UCLA next year, and our sources say Drake's given him pointers on how to handle all the attention and pressure that comes with being a star player.
