Bobbi Kristina Brown and husband, Nick Gordon, are lashing out after fans reacted to Bobbi Kristina’s super skinny frame.

Whitney Houston and Bobby Brown‘s daughter shared pictures of herself on vacation over the weekend in an ity-bity-black bikini.

Her husband Nick Gordon posted a pic of the 21-year-old newlywed with the caption, “I gotta bad b––––.”

When the Twitterverse and the media began commenting that she was too skinny, the duo lashed out with Tweets of their own.

“My baby is perfect the way she is,” Gordon Tweeted on Tuesday, peppered with a few choice profanities. “And for the record she was made that way why change I know she is beautiful.”

Bobbi Kristina joined her husband on Twitter in her own defense, saying she was built just like her famous mom.

“I am my mothers child! Have you ever heard of a #fastmetabolism ?” she wrote. “Damn, lol, it’s incredible how the world will judge you 4ANY&EVERYthing.”

Criticism is not something new to the newlyweds. They caused a stir when they married in January.

Brown and Gordon were raised as brother and sister when Houston took Gordon into her home at the age of 12, so when they announced their engagement, it created another brouhaha from the media.

As reported by People, Bobbi said her marriage to Gordon had the blessing of her grandmother Cissy Houston and said Whitney wanted them to be together.

“I would tear up, this is exactly what she wanted, us together,” said Brown.

However, other reports said that Cissy was furious over their relationship.

Apparently, Cissy told a close friend, “What they’re doing is incestuous.”

“Krissy has told her grandmother that she doesn’t need her blessing to marry Nick, and the more Cissy objects to the relationship, well that only cements Krissy’s decision,” Star magazine reported a source as saying at the time.
