The 21-year-old catwalk star took to Instagram where she shared the Hollywood icon's photograph.
"Rare moment alert. Momma Kim in the flesh. I have no idea how people are born this beautiful," Baldwin wrote, alongside Basinger's smiling photo.
The model-turned-actress also made her acting debut in the 2013 film "Grudge Match", where she played a younger version of her mother's character, Sally.
Baldwin is the daughter of Basinger and actor Alec Baldwin.
