And yet, as you sit opposite the girls, you can't help but warm to them. Yulia, the spiky-dark-haired one, is the bolshier of the two, full of back-chat (albeit in Russian - she can't speak English) and in need, it seems, of a decent meal. Lena, with her dyed red hair and moon-shaped face, is more circumspect. It is rare for the girls to give a full interview; rarer still for them not to be under the watchful gaze of their manager, Shapovalov. Both, it must be said, look much younger than their reputed 18 years of age.
