"She only wants good things for me," the Shameless star told ET's Cameron Mathison at the SAG Awards. "Acting and showbiz, theater, is at the core of our relationship. We met in the theater. We still talk about our roles with each other, we share each other's scripts, we critique each other -- it's not a good idea for most people, it could be world war three, but for us, it works."
He added of Huffman, "She's my biggest supporter and she's the smartest person I know. It's great to have someone like that in your corner."
