The entire family appeared on Good Morning America on Thursday, and Jep was asked how his 69-year-old father reacted to the baby news.

In 2013, Phil came under fire when he made some remarks toGQ magazine about black people living in the South before the Civil Rights era.

"I never, with my eyes, saw the mistreatment of any black person. Not once. Where we lived was all farmers. The blacks worked for the farmers. I hoed cotton with them," the Duck Dynasty star told the magazine at the time. "They're singing and happy. I never heard one of them, one black person, say, I tell you what: These doggone white people -- not a word!... Pre-entitlement, pre-welfare, you say: Were they happy? They were godly; they were happy; no one was singing the blues."

In September 2014, Phil clarified his comments to Us Weekly, saying, "I was just giving my experience.

They would sing spiritual songs as they were going across those cotton fields."

He added, "We don't look at people like black, white and brown. We're all members of the human race."
