Geez, we couldn't imagine how that happened. It's not like she's BFFs with Karl Lagerfeld or anything.
The ads will be released later this year, and since Diane was previously shot by Unkle Karl when she was the face of Chanel's Allure fragrance and Paris-Biarritz bag, it's almost guaranteed she'll be working it for his camera again.
We can't wait to see the campaign!
