The Dutch supermodel - who is married to British comedian David Walliams - couldn't believe her luck when she was asked to work for Calvin Klein in 2007 after being scouted on a Metro in Paris at the age of 15 and she still finds it an amazing experience every time she works on a big job.
She said: ''[It was] a major moment, when it all began to change. When I first did the jeans campaign, I was like, 'I feel just like Kate [Moss], so cool!'
''And the oh-my-God moments just keep on coming.''
Although Lara, 29, was voted number one on model.com's Top 50 Models list for two years in a row, the blonde beauty admits she doesn't see herself in that light and only feels attractive on certain days when her complexion is clear.
Lara - who is currently expecting her first child with David - continued to Marie Claire magazine: ''[I feel sexy when] I wake up and maybe my eye bags have gone, and I don't have any spots.
''[When I see myself on a billboard] I think to myself, 'Wow, I wish I looked like that.' ''
