Whitney Houston’s daughter Bobbi Kristina, 20, has announced that she is engaged to Nick Gordon, 24, amidst criticisms that the two are siblings.

The couple grew up under the same roof and the claim has been made throughout much of the their relationship.

In a post to her Facebook page, the reality star lashed out at her critics, writing:

"I'm tired of hearing people say, 'Eww you're engaged to your brother' or 'If Whitney was still alive, would we be together or would she approve of this?' Let me clear up something, we aren't even real brother and sister, nor is he my adoptive brother."

However, Houston did informally adopt Gordon when he was 12 and he spent most of his teens living with the family.

When the couple canceled their engagement in 2012, a source told Us Magazine that the family’s disapproval led to the decision.

The source said at the time:

"I think it has to do a lot with the family not liking Nick, considering he was a godson and then they became a couple.

"I'm sure there is a lot of, 'Would Whitney be okay with this?' going around."

The bride-to-be concluded her letter, writing:

"People need to seriously stop judging my relationship… Your opinions are yours and mine are mine.

"It is my life and not yours. The decisions I make have nothing to do with you. Goodnight."
