This August, she and Pratt are headed to Africa to "feed children and help build things." Cameras will capture their trek, but not for The Hills. Pratt says it's possible they could adopt a baby while over there, but Montag laughs that idea off.
"Not right now," she insists. "I think we'd be married before we do that."
Montag likes to think she and the Jonas Brothers are part of a new wave of positive role models. "As a parent, I would not want my daughter looking up to someone throwing money away, on drugs or coming out of rehab," she says.
But while Jesus preached forgiveness, Montag says "Hills" fans should not hold their breaths for a big reunion for her and Conrad. "I don't think people are ever going to get that," she says emphatically. Even so, if Conrad offered an olive branch, Montag would accept. "She'll always have a place in my heart."
A more likely scenario: Montag and Pratt will wrap up their time on "The Hills" after this season and launch their own MTV reality series along the lines of "Newlyweds: Nick & Jessica" — Montag's all-time favorite show.
Any concern such constant camera presence could lead her and Pratt down the same doomed path as the since-divorced Lachey and Simpson?
"I don't really feel that way," she says. "You're either going to make it as a couple or you're not. I love cameras, but the cameras aren't with us when we're falling asleep at night.
"The show's going to be about our lives, and it's such a blessing to be doing this."
