"I don't know when," the 32-year-old actress, who is currently filming The Girl on the Train in New York City, revealed in August. "We’ve got to give [Hazel] some competition at some point."
Meanwhile, the former Office star recently gushed over his wife, adorably stating, "The best days of my life started when I met my wife."
"That's the truth, it's not just me saying it because it sounds nice on a card," Krasinski, 36, told The Daily Beast. "She's one of the coolest people, she's so talented, she's beautiful, and she's certainly out of my league...When you're lucky enough to meet your one person then life takes a turn for the best. It can't get better than that."
