Social media was shocked to learn that the California woman, who looks incredibly youthful, is actually a grandmother. With the 38-year-old sharing that she often gets compared to her 20-year-old daughter Makenzie. “A lot of people mistook us for sisters, or twins, and were left baffled when I told them we were actually mother and daughter,” Desborough told the Mail.
