Olivia Palermo & Johannes Huebl Model For Mango

"The City" star and all-around fashionista Olivia Palermo is set to star alongside her boyfriend Johannes Huebl for Mango, Vogue UK reports. She told the British glossy that she was shy at first working with Huebl, "but then I remembered it was just him and I could just be normal -- so then it was really fun." Huebl is actually a model himself, having posed for Saks Fifth Avenue, Cole Haan, and Ungaro, among others. He and Olivia have been dating since 2008.

Poppy Delevingne and Scarlett Johansson will also be featured in the new ads. Some of Scarlett's work has already surfaced and may or may not have been Photoshopped. Olivia told Vogue that she wasn't yet sure where her ads would be featured.
