In an interview with In Touch, the actress, who is married to Jerry O'Connell, revealed that Dolly is "wild", and that Charlie is following in her sister's footsteps.
“Dolly always likes to stand on the highest platform she can find. She’s a climber, and Charlie is starting to investigate climbing as well, so I’m praying for no broken bones any time soon," she said.
"It's mind-blowing watching them develop their personalities!”
