Nadya ‘Octomom’ Suleman shares a new baby photo on Instagram to announce she became a grandmother. Nadya writes in her caption, ‘Thank you, my son and my lovely daughter-in-law, for giving us this beautiful gift!’ While she doesn’t specify which of her children is a new parent, Nadya referred to 21-year-old son Joshua as a ‘soon-to-be father’ in a birthday tribute last month.
