See Nicola Roberts' style evolution, now that she's a bonafide fashion expert

Following the news that Nicola Roberts is to host an actual genuine fashion television show, we thought we'd have a look at her style evolution - delving right back to heady days of Cheryl's corn-rows. Having closely analysed every single picture that's ever been taken of the singer since Pop Stars the Rivals, we think we can conclude that 2007 was the year she officially started looking great. Prior to that, it was all Nadine's fault, we're certain.
