If Jessica Sierra wants to stay sober, she'd better away from her old friends -- one of them told TMZ she'd do cocaine with the "Idol" reject again in a second.

TMZ TV talked to one of Sierra's sisters and one of her hometown buds -- who was with the now-pregnant Top 10 contestant the night she was arrested for disorderly conduct and resisting an officer without violence. They had been busy spending money Jessica earned from Vivid Entertainment for her sex tape, "Jessica Sierra: Superstar."
