JCPenney continues to shock and surprise us... in a good way.

The newest addition to its stable of brands? MNG by Mango.

Hot on the heels of partnering with the Olsen twins for Olsenboye, JCPenney has partnered with the Spanish fast fashion brand known for its affordable catwalk clothing, collaboration with Penelope Cruz and current ad campaigns starring Scarlett Johansson.

MNG by Mango will bring a "representation" of Mango fashion to the American retailer, becoming the largest contemporary brand on JCPenney's floor, selling career, casual sportswear and accessories.

By Fall 2010, the brand will launch in up to 75 JCPenney locations and hopes to be in 600 stores by Fall 2011, making it the largest rollout of any fast fashion concept.

"Fast fashion for the young, modern woman is our highest-potential business opportunity. said Myron E. (Mike) Ullman, III, chairman and chief executive officer of JCPenney in a release. "Having MNG by Mango exclusively will further establish JCPenney as a first choice destination for the best, affordable contemporary fast fashion in the U.S."

"Every time we bring Mango to a new international market, it has driven immediate, strong demand, and we have only begun to capitalize on the great desire for Mango in the U.S.," said Enric Casi, Mango's CEO in a release. "JCPenney is the perfect match for us to take advantage of the opportunity we see for the MNG by Mango brand in this market."

Mango currently operates 300 stores in 94 countries, 12 of which are in the US.
