TMZ Sports spoke to McMahon -- WWE's Chief Brand Officer -- about Rousey's future with the wrestling powerhouse.
"Ronda's been very public that she’d like to start her own family," McMahon tells us.
"Once she does that, our doors are absolutely open, our arms are open, we are very hopeful that Ronda will come back home to WWE."
She was champ for nearly 8 months.
But, Rousey -- who's reportedly under contract until mid-2021 -- walked away from the squared circle ... announcing she was taking an "impregnation vacation" in April 2019.
After leaving, Ronda said she loved WWE and the other Superstars, but slammed WWE fans ... calling them "f***ing ungrateful."
Bottom line -- it's obvious the McMahon family and WWE really want Rousey back ... question is, will she return??
