Ariel Winter's Mom -- I Do NOT Have Naked Photos of My Daughter

Ariel Winter's mother Chrystal Workman insists ... she does NOT have any nudie pics of her daughter Shanelle Gray -- despite allegations Chrystal tried to leak them to the media.

Chrystal said, "I have no naked photos of my daughter."

As we previously reported, a Hollywood publicist named Jonathan Hay claims Chrystal contacted him this week, and said she had nude photos of Shanelle she wanted to secretly release to the public.

TMZ broke the story ... a judge awarded Shanelle guardianship of 14-year-old Ariel in October after allegations Chrystal was emotionally and physically abusing Ariel.
