Following on from the success of Geordie Shore, MTV is hoping that its new gaggle of Welsh party animals will cause a similar stir.

The cast include a world champion kick boxer, a law student, a bricklayer and wannabe glamour models, who are hoping to score fame off the back of the series.
The trailer for the series features sexual content including a man shaking his face in a girl's cleavage, a girl grinding a blow-up sheep and a girl shaking her butt cheeks.
