Bobbi Kristina Brown has lashed out at critics of her recent dramatic weight loss. The newlywed, 21, sported a surprisingly skinny frame in a recent Instagram bikini pic, prompting fans to voice concern over her health.

Brown evoked her late mother Whitney Houston's naturally thin frame in defending the photos. "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." 

Her husband Nick Gordon also jumped in to defend his bride. "My baby is perfect the way she is," Gordon tweeted on Tuesday, adding a few choice profanities for bloggers and reporters. "And for the record she was made that way why change I know she is beautiful." 

This isn't the first time Bobbi Kristina's actions have spurred controversy. The aspiring actress had to defend herself against those who disapproved of her marriage to Gordon, who was known as Houston's de facto adoptive son and had lived under the late pop star's roof since he was 12 years old. "This is exactly what she would have wanted, us together," Brown said of her relationship with Gordon this past January, just weeks after they tied the knot. more
