In a new interview with Extra, Nick Gordon and Bobbi Kristina finally talk about their secret marriage and the negativity surrounding it.

“It put a fire in us,” Nick tells Extra. “The critics can say whatever they want to say…it’s like we have a force field and that s–t’s just bouncing off of it.”

Adds the daughter of Whitney Houston: “It lit a fire up under our ass and we went hauling.”

Last summer, Bobbi posted on Facebook that their engagement was back on, writing: “YES, we me nick are engaged. I’m tired of hearing people say ‘eww your engaged to your brother’ or ‘if Whitney was still alive would we be together or would she approve of this.’ My mom never adopted him. In fact, mommy was the one who even said that she new that we were going to start dating.”

Nick opens up a bit about his relationship with the singing superstar.

“She [Whitney] just treated me like she gave birth to me. She treated me like a son,” Nick said in the interview with Extra. “She made me promise several times to look after Krissy…and Mom, I will never, ever, ever break that promise.”

Adds Bobbi Kristina: “She wanted this. This is something she wanted to see.”
