The Kardashians' Body Secrets

This week's WHO

It was a holiday with a purpose when the Kardashian-Jenner clan hit the beach in St Barts, flaunting their new figures and happily snapping selfies. At six months pregnant, Kim Kardashian West bared her belly in a bikini top, confidently ignoring criticism of her weight from online trolls and tabloids. "I've learnt to love my body at every stage!" said the reality star. "No matter what rumours or comments you throw my way this time they truly don't affect me!"
