Braided hair seems to be having a red carpet revival this season. It was the hottest hairstyle at February's BAFTAs, then Rihanna turned up at the Costume Institute Gala with a full-on Rapunzel plait, now Nicole has made the style her own at the Billboard Music Awards.
While we weren't sure about Rihanna's uber-long locks we think Nicole has the style nailed. The messy finish combined with glowing skin and a classic Dolce & Gabbana dress make the star a red carpet winner.
You can see all the outfits from the night in our Billboard Music Awards gallery and don't forget to let us know what you think of Nicole's hairstyle below.
