Bloom couldn't stop gushing about his son while chatting with ET at the premiere of Pirates of the Caribbean: Dead Men Tell No Tales last month.
"I'm so in love with being a dad," he shared. "I'm a very lucky man."
"I have to say, [he opened] my heart in a way I never thought was possible," Bloom added. "I just really thought I was never going to open my heart and he did it. It was amazing. Everything they say is true! Having a child changes everything."
