The show follows nine South Wales youngsters as they relocate from the countryside to Cardiff in a bid to achieve their career ambitions.
They will all live in a house together, with bosses and mentors Jordan and AK trying to keep the cast on track as they struggle to balance their partying with their professional lives.
AK is a former naval officer who now works as a glamour model and photographer, while Jordan is a promotions manager.
The cast includes a gay rugby player, a three-time world kick boxing champion, a law graduate-turned-glamour-model and the 'Welsh Beyoncé'.
The Valleys premieres on MTV in September.
