DJ Khaled better hit up Lil Baby (remember?) for some jump shot tips ASAP ... 'cause the rapper/producer hilariously airballed a 3-pointer during the Heat's playoff game on Sunday.
The "We The Best" star was on tap for the first game of Miami's 1st round series against the Hawks ... and decided to get in a "practice shot" during a break in the action.
In the video, you see Khaled take one dribble to gather his shot before launching a 3-pointer from the top of the key .
