After hearing the cheers for Lucien, Amy wanted a mag deal involving him - although he's not her type at all. But Lucien
appeared to start taking it seriously and to think it was a romance rather than a fauxmance.
At that point Amy decided to tell him "We're just mates" and has (presumably) dropped the idea of a mag deal. Lucien has indicated he is gutted, but his face and body language indicates he is probably acting.
That's my take on it anyway!
Oh, and there now a Hate Amy page on Facebook because of all this, we are told by the Daily star.
