Last year, after welcoming Wyatt into the world, Cooper opened up to PEOPLE about how he had been enjoying every minute of fatherhood ever since the birth of his son. "When I was 12 years old and knew I was gay and thought about my life, it always upset me because I thought, 'I will never be able to have a kid,' " Cooper said in PEOPLE's cover story for the magazine's first-ever Pride issue. "This is a dream come true." "It feels like my life has actually begun," Cooper continued. "And I sort of wonder, what was I waiting for?" "This is a new level of love. It's unlike anything I've experienced, and yet it's also very familiar and incredibly special and intimate," he added. "It's really extraordinary."
