At the ripe age of 3, their son Liam has launched his own Twitter account, LiamsWorld, where, with the help of his famous mom, he updates his 14,000-plus followers to his best one-liners.
"The response was not what I expected. It was insane," Spelling, 37, tells PEOPLE, adding that the toddler got more than 10,000 followers in just six hours after launching the page earlier this week.
Some one-liners that have had his parents and fans laughing: "Mama the moon ate the sun and made it dark. Will he burp him up tomorrow so it'll be a nice day?" And, "I love making jello castles. Jello wiggles and parties in my tummy."
That humor, Spelling says, has "really lifted" Dean's spirits while he's been recovering from a motorcycle accident.
"Once Dean came home from the hospital, Liam told Dean, 'You have to stay in bed. Doctor said you're sick. You have a boo boo,' " she recalls. "Dean is slowly recovering. He has a long road ahead and is still in a lot of pain. He's just taking it day by day, and the kids and I are good nurses!"
