"George will be an absolutely wonderful father. Amal will be—and already is—a magnificent mother!" he told Good Morning Britain, according to E! News. "I'm constantly amazed by her. She is an incredible woman."
The new grandfather also threw in a joke about his son. "George certainly married up!" he added. Clooney obviously has a sense of humor. (Maybe that's somewhere in his grandkids' genes, too.)
The elder Clooney met his new grandchildren on Tuesday when he FaceTimed George and Amal two hours after the twins were born. Although there are no photos of the newborns yet, he teased that Alexander has George's nose and that both babies have dark hair.
We'll be waiting patiently for those photos.
