Adriana Lima was worried about appearing in lingerie after giving birth.

The Brazilian supermodel almost backed down from the Victoria's Secret Fashion Show - held in New York in November last year - after giving birth to her second child, Sienna, only eight weeks before.

She said: ''I had no idea if I was going to make it, honestly. The hormones - you don't know how your body is going to react.''

Adriana, 31, also has three-year-old daughter Valentina with husband Marko Jaric, and admits its not easy being a model and a mother of two.

She said: ''It's not easy with two children because you basically have to go to the gym or work out at home when they are taking a nap. As a mom, you feel guilty leaving because you want to be with your children all the time.''

Adriana is currently the fourth highest paid Supermodel in the world, earning an estimated $7.3million from may 2011 to may 2012. She also made headlines last year when she became the first pregnant model to appear in the famously raunchy Pirelli calendar's 2013 edition.
