Blueface is publicly fending off his own mother, Karlissa Saffold Harvey, from his tender loins … according to the “Thotiana” rapper, she wants to buss it open for him!!!

The bizarre rant came out of the blue on X, but Blueface appeared to be adamant he doesn’t want his mother meddling in his affairs any longer.

Blue boldly wrote, “Mom we could never have sex I’m not into that please stop being so invested in the women I’m laying down with it’s kinda weird like you jealous or some we can never lay down together you not my type !”

He continued … “Anytime you guys see my mom targeting my lady friends please let her know ‘this is what your son is talking about’ cuz I don’t get the correlation…I just want her to stop sabotaging my relationships !

“My only problem is keeping it to real Ina fake world idk how to be like y’all,” he writes in another tweet.

BF’s comments have interesting timing on the heels of his short-lived ‘ship and breakup with Hazel-E.

We caught up with the “Love & Hip Hop” star out with her new man, and she told us flat-out she feels Karlissa wants to bang Blueface all for herself — Cane Corso doggystyle!!!

Karlissa is demanding Blueface give her an equally public apology, but says she’s willing to cut him out of her show for the sake of cutting out the shenanigans.
