The young lady in this picture has clearly noticed that her big sis is having a whale of a time touring the world, wearing fabulous outfits and dating hot men, and now wants a piece of the action too. Yep, this is Rachael Coyle, sister of Nadine from Girls Aloud… but if you couldn’t work that out for yourself, you might want to get your eyes tested – they could be twins! Rachel is carving out a modelling career and is the new face of Verlocke hair extensions. We wonder if she has Nadine's gazelle-like legs and bizarre transatlantic accent too...
Whose sis is this?
