'The Real Housewives of Atlanta': Never Before Seen Footage Of Kim Zolciak And Kroy Biermann's Relationship (VIDEO)

After all the bubble baths, the wedding, the alone time and the candid chats with Kim Zolciak and her husband Kroy Biermann, viewers of "The Real Housewives Of Atlanta" (Sun., 9 p.m. EST on Bravo) could have been forgiven for thinking they'd seen it all.

But they hadn't. An entire episode Sunday night was dedicated to airing exclusive unseen footage of the pair and their relationship.

There was a heartwarming moment of Kroy chatting with Kim's daughters before he married their mom, reassuring them that they could count on him for anything and that he was in it for the longhaul.

There was also a behind-the-scenes glimpse of the happy couple doing their first photo shoot with their newborn son.

When it came to disciplining the children, Kroy seemed very much the more mature head in the household.

When he scolded stepdaughter Brielle about texting in school and encouraged her to work hard, she quipped, "That's the only thing school's taught me, is how to text without looking."

His response? To cancel her cell phone account. All Kim could do was shake her head.

The drama continues on "The Real Housewvies Of Atlanta," Sundays at 9 p.m. EST on Bravo.
