EXCLUSIVE

We've learned ... DJ's been getting close with Michelle Maylene (34B-24-32) ... star of such films as "Da Vinci Load," "Fine Ass Bitches 4" and "Slant Eye for the Straight Guy 2."
Sources tell TMZ Sports ... the two are not "official" or anything -- just enjoying each other's time. They're currently in Hawaii where DJ is playing in the Pro Bowl.
We broke the story ... DeSean's ex-GF Chantel Jeffries was the passenger in Justin Bieber's Lambo when he was arrested last week.
Apparently, DJ has moved on.
