Devin Booker turned the toughest shot in the Suns' playoff game Tuesday night into the cutest ... dapping up a baby to celebrate a wild make!!!
The Phoenix star's adorable interaction with the courtside toddler happened after he drilled a stepback jumper to end the first quarter of the Suns vs. Pelicans game.
Booker dribbled to get some space and knocked down a 2-pointer before the buzzer sounded ... and then he fist-bumped a toddler!
The scene was super sweet, Booker was gentle with the baby's little knuckles -- and, his own girlfriend, Kendall Jenner, appeared to love it all too!
