Bobbi Kristina Brown is planning a "fairytale" second wedding.
Whitney Houston's daughter secretly married her fiancé Nick Gordon earlier this month, despite controversy over their unconventional relationship since Nick was raised as her brother when the late superstar took him into her home 12 years ago.
The couple now hope to prove the sceptics wrong when they celebrate their commitment to one another for a second time with a big wedding later this year.
Bobbi told The Sun newspaper: "The criticism of our relationship only made us stronger. It lit a fire under our ass. We are officially married now but our wedding was just very low-key. But I can say that we're planning a big wedding later this year.
"It's going to be very royal, classic and beautiful - just a phenomenal ceremony. We're going for the full fairytale."
The 20-year-old aspiring singer says Whitney's death from an overdose in February 2012 brought her and Nick together and she thinks the 'I Will Always Love You' hitmaker would have been excited about the big day.
Speaking on US TV's 'Extra', Bobbi, 20, said: "She wanted this. This is something she wanted to see."
She added: "Losing mum brought us together. Nick has been there for me - he's my backbone. If my mother could see me now she would just be so incredibly happy. I can just see her - she'd be running around fussing about the wedding."
Meanwhile, Nick, 24, silenced critics by insisting he will never break his vow to Whitney to protect her daughter.
He said: "Me calling [Whitney] mom, this where everybody gets the ['brother and sister' thing from].
"We were young. I looked at Krissi like a little sister, she looked at me like an older brother. Whitney taught me how to be a man, how to respect women. I owe everything to her.
Nick added: "[Whitney] just treated me like she gave birth to me. She treated me like a son. She made me promise several times to look after Krissy ... and Mom, I will never, ever, ever break that promise."
Nick, now in his 20s, was taken in by Whitney when his mother could no longer care for him, before he was a teenager. He was never officially adopted by the star and he and Bobbi - whose father is singer Bobby Brown - have no blood relatives. - Bang Showbiz
