“We started going and doing it like a few months in because the world was shut down,” she said. “We knew we wanted to start a family, and I was like, ‘This is perfect timing. Usually, I’m on a plane 250 days out of the year, and let’s just get all of the eggs stocked and ready,’ and we have tons of them just waiting.”

Congratulations to the new mom and dad! We can’t wait to see more of him!
