Perrie Edwards Little Mix's Perrie Edwards has had no sense of smell since birth, so perfume isn't such a big deal to the 29-year-old. Back in 2014, Edwards said she wears Christina Aguilera by Christina Aguilera (£16). "That's what everyone says I smell nice wearing, so I stick to the same one. I don't trust anything else," she explained. Image Source: Getty / Karwai Tang Christina Aguilera by Christina Aguilera £16 from superdrug.com Buy Now
