I don't dislike Lucy but it's clear that she has a major princess complex and as such strives very hard to be the thinnest, bustiest (although she'll never top Billie Faiers), tannest, or tops in whatever field of competition they have going.
For some reason the other cast members view her as a bit of a little sister (she is one of the youngest among them) and they seem to be very tolerant of her alpha female routine even as Lucy shows them up - with the notable exception of Lauren Pope who clashed with her in the past over Kirk Norcross. Pope and Chloe Sims are always at the ready to get the claws out with any perceived threat...the clock is ticking loudly for both...nose jobs (Popes looked so much better before) and botox only hold off the inevitable for so long.
