Meghan Markle is offering a glimpse at her mother-son weekend with her 6-year-old, Prince Archie. Meghan, 44, shared rare footage of Archie to her Instagram Stories on Sunday, January 18, as they visited a rhinoceros exhibit at a local zoo. "On average, black rhinos can weigh up to 3,000 pounds, but his dad wasn't quite 3,000 pounds," a zookeeper explained while Archie fed a baby rhino a piece of grass. "We don't know [how big he will get]." In the clip, Archie was dressed casually in a gray pullover hoodie and showed off his auburn locks.
