Best celebrity hairstyles of 2012: september

But the biggest comeback of September 2012 was arguably Downton Abbey - and as the series slinked in to the roaring twenties, all eyes were on the Grantham girls as they embraced short hair and shingles.

Here are our favourite celebrity hair looks from September 2012...

Ladies Edith, Sybil and Mary may have embraced the 1920s to varying degrees on Downton Abbey but their off-screen style is in-demand too with all three girls enjoying front-row seats at fashion weeks and high-profile appearances on TV talk shows across the globe.

While Jessica Brown Findlay and Michelle Dockery go for all-out glamour with their chocolate box bouncy curls, it's down to Laura Carmichael to stand out with her short, sharp strawberry-blonde bob.

Look to love: When the on-screen sisters appeared on Jonathan Ross's ITV chat show we got a good look at how their sisterly style looked in real life - glossy and perfectly groomed, just like a 21st century update on their immaculate alter egos.

Following her breakup from Robert Pattinson, Kristen was on the receiving end of some particularly harsh criticism from dedicated Twilight fans disappointed by the big-screen couple's real-life break.

But proving that living well is the best revenge, Kristen made the campaign trail for her new film, On The Road, a veritable catwalk of stunning, sexy, single-girl looks.

Look to love: Immaculate makeup, a spectacular dress and glossy, groomed hair pulled back in a high ponytail.

We're more used to seeing Kristen dodging a hairbush, so this dressed-up look made for a pleasant surprise.

The slightly wet-look quiff adds Kristen's trademark touch of nonchalant cool.

Jessie J followed in the footsteps of Rihanna and Katy Perry in choosing a more subtle look for the latter half of 2012.

Just like her fellow chart-toppers, Jessie ditched the colourful hairpieces and elaborate styling and opted for a more natural colour and relaxed finish.

While we're sure her on-stage look will be as bright and bold as ever, Jessie's dressed-down look became more about classic glamour than edgy individualism with the star telling ELLE magazine that her 'scary, cartoony' look was now behind her, replaced with something altogether 'more feminine'.

Look to love: Looking radiant with brunette locks styled in natural-looking waves, Jessie looked almost unrecognisable outside the BBC Radio 1 studios in October.
