One source claims the 18-year-old was actually bullied for being there -- apparently not everyone thought she earned the right to walk the shows!
The insider spilled:
The Kardashians stripped down to their undies for another photo shoot.
Kourtney posted on her blog:
"My sisters and I did a sexy shoot for our Kardashian Kollection lingerie line! I love this shot of the three of us. I’m wearing our gorgeous stain glass bustier bra and satin stain glass briefs. It’s one of my favorite sets from the collection… really fun, colorful and sexy, but still comfortable, which is so important!"
The shoot went down back in February, so obviously Kourtney's bump was 'shopped out amongst other things.
