"I don't know, let your kid ride his Tonka truck all up and down the dirt road for as long as he wants to because one day you're gonna be grandma. You're not gonna be doing all that s---," Biel said. "Or maybe you will. I hope I'm the grandma who drives around with the Tonka trunk. A Power Wheel. I hope so. Anyway, here's to looking old," she continued.
