"I think anybody in our situation would do the same," Jordan explains. "Family matters are sensitive and private."

While the 27-year-old former football player didn't want to make this part of his life public, he reveals that he's shared a great deal with JoJo. "Of course, I knew what I signed up for. I knew it was a show where I would have to be honest," Jordan says. "I knew I wanted to be honest with her, and share with her everything I could about my life."

He adds, "We're just excited about this next chapter."

Jordan and JoJo also open up to ET about dealing with tabloid scrutiny while trying to keep their relationship status a secret leading up to The Bachelorette season finale. "There were so many times where I would just call him sobbing, and there were times when he would break down," JoJo admits of seeing stories about herself. "We were both like, 'This is tough. What can we do? We can't do anything.'"

As for reports that they were corresponding on Twitter before they met on the show, the couple insists that never happened. . "It would've been a lot easier to find him that way. No, I have no clue where that came [from]," JoJo says. "The only reference to his name that I even knew was, I think a week before we started filming, where he got leaked, and I remember seeing his photo and being like, 'I wonder if that guy's gonna show up.' That was it."

Jordan admits that he never watched The Bachelor or The Bachelorette and didn't know what to expect when he met JoJo. "I did not know anything about it," he claims. "I didn't know anything about her until a couple days before, and then I found out when everybody else did that she was going to be the Bachelorette."

Further responding to rumors that their on-screen romance was "rigged," JoJo exclaims, "I don't know where it comes from! No, I never met him, never saw him, until that moment he stepped out of the limo."

"It was kinda sneaking around a little bit."

JoJo chimes in, "Our producers don't know!"
