What were X Factor contestants wearing at last weekend shows?

Rebecca had mani and pedi with DS Radiance with a top coat of Kyoto Pearl
Mary had the same as last week – Big Apple Red with Black Shatter  - as she was in bed with flu.
Even the guests on this week’s show sported OPI for their performances too:
Grace Woodward wore DS Radiance with Black Shatter, Konnie Huq wore Rosy Future Axxium Gel and Alexandra Burke had Barefoot in Barcelona Axxium Gel.
