Leighton Meester is Missoni's new face and will appear in the label's ads during the spring/summer 2011 campaign. The first photos have been revealed with Leighton joining the Missoni “Family & Friends” special campaign.

It seems that the “Gossip Girl” star, Leighton Meester appears in the Missoni spring/summer 2011 campaign in a very girly, playful ad, riding a rocking-horse.

Besides the beautiful American actress, this unique campaign called “Family & Friends” features Missoni family members Tai and Rosita, Vittorio, Luca and Angela, Margherita, Francesco, Teresa, Ottavio, Marco and Jennifer, but also friends and different celebrities such as Camilla Al Fayed, Andrea and Charlotte Dellal, Jaquetta Wheeler, and famous artist Sir Peter Blake.

In the Missoni "Family & Friends" campaign we can also see socialites Tatiana Santo Domingo and Eugenie Niarchos, Browns founder Joan Burstein, and models Jasmine Guinness and Jade Parfitt.

Speaking about this campaign, Angela Missoni told "Vogue" Itala that "we were inspired by ‘St.Pepper Lovely Hearts Club Band’, by that record cover conceived by the great British pop artist Peter Blake. A work that, in my opinion, perfectly summarizes the spirit of our collection, its playful shapes, ‘cut out’ and silhouetted against space. I have therefore asked the great artist to realize a big collage of portraits for our campaign. And, to my great joy, he accepted."

Rumors about the actress' collaboration with the famous brand started in the moment when Meester was spotted wearing Missoni regularly. The spring/summer 2011 campaign was shot by Juergen Teller and in one of the photos Leighton appears on a rocking-horse having a playful attitude and smiling. Moreover, a video directed by Mel Bles was released in which the family and friends are the main characters.
