In the first of tonight's two BBC3 pilots, Leo Richardson's stage play transfers to the screen in a riot of txt speak, Lambrini and adolescent angst like a teenage Sex And The City set in the suburbs of Croydon.

Holliday Grainger plays the beautiful but slutty Dirty Debbie, whose scatter-gun approach to love wreaks havoc among her more sensitive friends and neighbours.

Among the grown-ups look out for Sharon Horgan, unrecognisable as Debbie's Auntie Pat, while the young cast are all eye-catching and plausible, like a walking manual to noughties etiquette. "I can't follow everyone who follows me (on Twitter)," complains the lovely Ben. "How would that look? That's like Facebook."
