Looks like Grandpa spilled the beans on the exciting news!

Jason Bateman and his wife, Amanda Anka, will experience their own "change-up" as they become parents for the second time. "I'm going to be a grandfather again," Amanda's father, Paul Anka, revealed to ET Canada.

The proud grandpa even let out the sex of the baby: "another baby girl" will be joining the family of three. The Change-Up actor Jason, married to Amanda for 10 years, already have a 4-year-old daughter, Francesca. When it comes to parenting, though, Jason believes "patience" is a lifesaver!
