"You know, I didn't do anything ... and I'm so tired," the Vinyl star said. "I think I've gained 28 pounds since Monday."
The couple named their baby Rocco after the patron saint of the sick, or "patron saint of made guys," as Cannavale joked.
The 45-year old actor also revealed that his idol-turned-card-playing-buddy Al Pacino sent the couple a diaper cake to celebrate Rocco's arrival.
"It was so sweet. It was a big cake made out of diapers," Cannavale explained. "For your boy," he added in a Pacino voice.
