Just as they did with Giudici Lowe’s first pregnancy, the spouses opted not to find out the sex of their second child until his birth.

In fact, they were split on their guesses, with the mom-to-be thinking blue and Lowe retracting his initial gut feeling of the same in favor of a daughter.

“I see this face and now I’m starting to lean towards a girl. I think I’m changing my mind. I’mgoing to bet on girl,” he told PEOPLE earlier this month.
