Here’s what the 36-year-old 30 Rock actor had to share with the mag:

On being openly gay in Hollywood: “The more it happens, the easier it is for others, although I do understand why some actors choose not to come out. I have several famous friends who are still in the closet.”

On working with Alec Baldwin: “I’ve learned to be totally comfortable around Alec Baldwin, but he used to scare the crap out of me. He’s so alpha male. He’ll move you out of the way if you’re in his light, and one time I thought he was done talking and I started to say something and he put his big beefy hand on my arm to silence me.”
