As she rose from out of the number 2012 London Olympics bus to perform Led Zeppelin's Whole Lotta Love with legendary guitarist Jimmy Page at the closing of the Beijing Olympics, Leona Lewis looked cool and classy. And her coolness was helped by one of the most fashionable nail polish colours around, a bright, fluorescent pink from the hottest name in nailcare, Essie, which we've seen on lots of fashion-forward nails in London recently. In fact, it's been so popular, it's sold out. So you can now only get it as part of a fabulous foursome with a similarly fluorescent purple, orange and yellow – Neon 4 To Go Mini Pack, £14.95, which is available from hqhair.com. Get it before it goes.
