-_- ''Bobbi Kristina'' and husband ''Nick Gordon'' blast critics who said she was too skinny ??

Bobbi Kistina has hit back at critics of her weight after a recent bikini snap, while husband Nick Gordon responded to Twitter users in a foul-mouthed rant.

The pair - who got married earlier this year - were blasting online trolls who attacked Whitney Houston's daughter for being too skinny in a bikini shot of her by the pool.

Bobbi was firm but fair with her retort, insisting people shouldn't be judged for how they look.

She wrote: "I am my mothers child ! Have you ever heard of a #fastmetabolism ?

"Damn, lol it's incredible how the world will judge you 4ANY&EVERYthing (sic)"

However, Nick wasn't going to hold back, unleashing an angry tirade on critics with a few choice words.

He ranted: "Working out Eating right and loving life is how my women keeps her body nobody cares that you are concerned what important is she is comfy."

So far so good...wait, what's that?

"My baby is perfect the way she is. Y'all reporters on my **** can **** my ****. MADD cuz your ***** is a 400 pounder."

Wow...well then!

The couple's relationship had been seen as controversial, after the pair grew up together in her mother's house, but Bobbi previously clarified their relationship.

She said: "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. My mom never adopted him."
