It's Draya Michele's birthday, but it's Jalen Green who's enjoying the cake ... 'cause the Houston Rockets hooper wished her a special 40th by sharing a pic of himself grabbing her backside in a lovey social media post.
22-year-old JG gave the special shout-out on Thursday ... saying, "Happy Pday to the realest on my side. I love you."
The last three words are obviously a big deal ... and goes to show just how serious the two are, despite all the chatter surrounding their relationship.
