The adorable couple stepped out together for An Unforgettable Evening, a gala fundraiser benefitting the Women's Cancer Research Fund in Los Angeles on Thursday, where they stopped to talk with ET's Denny Directo about their adorable grandkids.
"When you have grandkids, if you're with one of them -- or all three of them – look, there's no book, no radio, no TV. You're going to be entertained by them every moment that you're there," Hanks marveled. "Sit back and watch the show!"
However, the couple admit that their grandkids aren't necessary as enthralled by them.
"I think they just put up with us," Hanks joked.
"Sometimes they just look at us like, 'What?'" Wilson chimed in.
