She told People at the Miami event for the launch on Wednesday: “I was doing IVF during the shoot."
According to her, 'I was getting my shots and everything in Zanzibar, I had a little medical kit. It was hard because you bloat from it, and you bruise – if I hit the wrong area.'
She also explained that they would cover any marks with bruises for the photos.
The 30-year-old wife of John Legend, went on to say that she would consider posing pregnant, but not for personal use.
