Nicki showed off several unique hairstyles over the course of 2011 but this blonde 'do, complete with big frizzy pigtails, suited the 'Pink Friday' rapper perfectly. Nicki has spent the past few months teasing the launch of her second album 'Pink Friday: Roman Reloaded' which will be released on Valentine's Day 2012.
The 'Glad You Came' singer is well known for his immaculately cropped hair and 2011 was no exception. The Wanted star is currently getting ready to head state side with the rest of the band for a US tour in early 2012 before returning to the UK for a stadium jaunt across the country.

The X Factor judge Tulisa ditched her blond tresses just in time for the start of ITV1's reality series earlier this year and returned to her natural brunette colour.
