Just a few days after announcing I was pregnant, we did this shoot for the @voguemagazine iconic September issue. I was so energetic that day but then I remember being totally exhausted and needed to take a break for an hour. I was still trying to understand this whole pregnancy process. Nowadays I have no ankles or toes and my fingers resemble sausages but it's moments like this that are captured by @mariotestino that makes everything worthwhile. Dress by my love @donatella_versace
