So, Shaquille O'Neal was on his way to the gym in L.A. ... when all of a sudden he got caught up IN JONAS BROTHERS MADNESS!!!!
It's hilarious ... Shaq starts off asking our guys why hundreds of people are screaming and going crazy across the street -- and when he finds out it's all because of a Jonas Bros. event, he LOVES IT!!
But we also talked hoops with Shaq ... specifically about Drake, who's been heavily criticized for taunting Golden State Warriors players and going crazy on the sidelines during the NBA Finals.
