The thing about celebrity doppelgängers is that you probably have to do several double takes if you see one. Is that Ariana Grande or a 21-year-old Alexxa Morgan from California ? Are you really looking at Evan Rachel Wood or is it just Avril Lavigne? But what happens if you are an A-lister and have not one, but two lookalikes? That's exactly what has happened with Selena Gomez.
