Duck Dynasty's Phil Robertson has been unmasked as a historic cheater after a woman claiming to be his daughter came forward.
The 74-year-old religious patriarch had an affair after marrying his wife Miss Kay, which resulted in the birth of a woman named Phyliss, now aged 45.
But he had no idea his daughter existed until she wrote a letter to his sons Al and Jase explaining who she was.
Speaking on the Unashamed podcast this week, Al revealed he had initially dismissed the letter from his half-sister because her birthday was in the 1970s - when Phil had renounced his philandering ways and committed himself to the church.
"Well once we get into that and start looking at it a little more deeply, I'm like, 'Oh woah, woah... there might be something to this,'" Al went on.
"We both concluded, this is not one of those frivolous things we've got," said Jase.
The sons agreed they would have to approach Phil with the letters to get to the bottom of the decades-long mystery of Phyliss' paternity.
"I started thinking, there's a 45-year-old woman out there who doesn't know who her dad is, and she's looking," Al said.
"And I thought, even if it's not Dad, she needs to know it's not Dad."
When Phil took a DNA test, the results showed a 99.9 percent match with Phyliss' test.
The pair agreed to meet up and Phyliss has now been introduced to the Duck Dynasty family - while Phil remains married to Kay.
"We know that in all things — in all things — even sin, God works for the good of those who love him who have been called according to his purpose," Phil told the podcast.
"It's a pretty cool explanation of redemption, reconciliation, love. As it turns out, 45 years, you have a daughter that you don't know about, and she has a father she doesn't know about. Forty-five years, that doesn't sound like very long, but you say, that's a while. So finally, after all those years, we come together."
His other son Jep, who was also on the podcast with brother Willie, said he was "so excited" to meet Phyliss as he had always wanted a sister growing up.
"It was like a dream come true," he added.
Phil - who came to fame as head of the Duck Dynasty family on their reality show - has been outspoken in the past about his religious views.
He was temporarily suspended from filming the show in 2013 after making graphic homophobic comments about gay people, including that they were "sinners", and similar remarks about racial segregation laws.
