The Mad Men star grew up in rural Sioux Falls, South Dakota and one weekend her outdoors-loving mum packed up the family for a short getaway in the woods.
However, Jones reveals the trip almost ended in disaster due to a near-fatal brush with Mother Nature.
The Emmy Award-nominated beauty says, "We went camping once as kids. It was a flop. There was a tornado. It's South Dakota... (the weather patterns are) very random. My sister Jina almost got blown away. I'm not kidding. After that we got in the car and went home."
