Hopie Feek is opening up about her fraught relationship with Rory Feek, after announcing earlier this month that he is not her biological father.

He has responded to tell his side of the story.

Hopie Feek says she's gotten to know a biological dad she never knew she had, and is feeling 'unconditional love' like never before.

Including four mugshots!

"You don't get to tell your father how to live his life or how to raise Indiana. Shame on you!!" the message reads.

Feek says he was hoping to talk with his estranged daughters, but Heidi Feek says the unexpected visit was 'intimidating.'

Feek says 10-year-old Indiana has "never been more loved or better cared for than she is right now."

Feek's late wife Joey would "never stand for" his behavior today, one source says.

He shared a touching moment that was the highlight of the ceremony.

He surprised his new bride with a special song.
