Angelina Jolie and Brad Pitt are keeping their twins underwraps because of Knox and Vivienne's fragile health, a new report claims.
The youngest additions to the Jolie-Pitt clan – who turn 1 next month – have been seen in public just once this year, when they were whisked through a Tokyo airport in January.
According to Life & Style, both babies suffer from medical issues.
"They’re both hypersensitive,” says an insider. "Knox has trouble holding down his food. He spits up nearly every meal."
Vivienne apparently suffers from allergies: "Right now, she’s on a lactose and gluten-free diet, and she's still underweight," says the source.
Angelina and Brad reportedly feel that the twins are better off behind closed doors for now.
"Because of their delicate state, Knox and Vivienne need to be kept away from anything they could possibly be allergic to,” the insider explains.
“That’s a lot easier to do when they’re home and in a controlled environment.”
