Alessandra Ambrosio was two months pregnant when she took to the catwalk to tape the Victoria's Secret Fashion Show at the beginning of November (11) - and no one knew.
The sexy supermodel reveals she considered pulling out of the project, but instead decided not to tell anyone she was expecting - and hope producers didn't notice she was a little heavier.
Ambrosio, who revealed she was pregnant on Tuesday (27Dec11), tells UsMagazine.com, "When I first found out I was pregnant I thought, 'Oh my gosh, I don't think I'm going to be able to walk on the show,' and I didn't tell anybody so no one knew at the show that I was pregnant.
"A week before, I told my booker, 'I don't think I'm going to be able to fit into the clothes because I gained a few pounds already!', but we were just quiet. I cut all the sugars and sweets 10 days before and I got my trainer... and we were doing lots of glutes and arms and back exercises."
