Even Kim smiled and she herself has admitted that she doesn't do that very often (because it causes wrinkles). So, why was Katy so stingy with the smiles?
According to a new report by HollywoodLife, Katy might have been embarrassed by Kim's boob-baring wardrobe. "Katy Perry looked mortified when she ran into Kim at Givenchy and people wanted to take pictures of them together," their source revealed.
"Kim was in one of her boob exposing outfits and you could tell Katy wanted to get away," they continued. "Katy has worn revealing outfits in the past but even she thinks that Kim is not dressing appropriately for Paris Fashion Week."
Yeah, cause we were just gonna say...
According to the site, Katy and other stars like Salma Hayek and Kristen Stewart just thought it was a little out of place at the shows.
Here's a pic from the Lanvin show, where Kim is wearing a see-through mesh top and everyone else DOES appear to be dressed more modestly. Do you guys think she looks out of place or is she just staying true to her super sexy image?
