They're currently expecting their first child together.

"I'm more excited about this than I've ever been about anything in my life," he said of his impending fatherhood. "And I'm also more terrified about it than anything I've ever been in my entire life. If I'm too confident, then I'm just kidding myself."

The Last Word co-stars began dating early last year and got engaged in September.
