Wendy Williams is back on the wagon and she's ready to return home ... at least according to her son.
Kevin Hunter Jr. shared a healthy update on his famous mother Monday, saying ... "She's sober and wants to come home."
Unclear where Wendy is living now -- her legal guardian Sabrina Morrissey filed court docs claiming WW is "cognitively impaired and permanently incapacitated" -- but her son says the family is fighting to bring her home.
Kevin adds ... "Isolation is killing her faster than anything else."
Wendy's last two public outings have been down in Florida ... including a trip to Miami for Kevin's graduation from Florida International University.
New video from Kevin's big day shows Wendy getting ready for the commencement ceremony ... she's getting her nails done and getting a new wig.
It's good to hear Kevin saying Wendy is sober ... her former struggles with alcohol were featured on her Lifetime documentary, including a scene where she polished off an entire bottle of vodka.
As we reported ... Wendy was diagnosed with aphasia and dementia in May 2023, a year after being placed under legal guardianship to manage her health and finances.
