Rob told People that the baby, born July 4, "tends to be a bit of a night owl like her daddy." Overjoyed with his new arrival, he added, "She is a perfect baby and we could not have asked for anything more. We are over the moon with happiness."

Weighing in at 6 lbs, 11.5 oz, Lucia Rose's middle name is a tribute to Rob's late grandmother who died Fourth of July.

Same day the baby was born, his grandmother died.
