Blac Chyna's Mom -- I Don't Care About Kylie ... I Want Tyga Back with My Daughter!

Tyga's dalliance with 17-year-old Kylie Jenner don't mean a thing to the mother of Blac Chyna ... who tells TMZ she desperately wants her grandson's parents back together.

Shalana Hunter reunited with Tyga backstage at his concert last weekend in D.C. -- so the two clearly still have a relationship. She says she has "no feeling" about Tyga's relationship with Kylie, but she wants Tyga and Blac Chyna to work things out ... blaming the initial breakup on the follies of youth.

Hunter says she still thinks of Tyga like a son-in-law and has no ill will ... adding Tyga treats her with nothing but respect.
