Katherine Jenkins Gets New Hairstyle AND New Album Deal

How does a girl celebrate a new record deal and a "new chapter in life?" If you're Katherine Jenkins, you ditch your platinum-blonde hairdo and embrace the dark side.

The singer has taken to Instagram to share pictures of her new "almost brunette" hairdo, writing: "Going back to my roots... Musically! #Announcement #Decca #Music #Hair."

She has just renewed her relationship with Decca records, and announced she will be focusing more on her classical roots than pop ones.

She celebrated the new deal - and her new look - at the Ritz hotel on Monday, and tweeted a pic of her gorgeous Stella McCartney dress: "From today's new record deal announcement & 10 year anniversary brunch. Dress by Stella x

She paired the frock with nude patent Louboutin heels, and, while there, talked to the Mail Online about her changing appearance, saying: "My mum loves my new hair and us girls love a bit of change. I've been enjoying trying out different shades of make-up and dressing differently. I'm having so much fun with it already."

Katherine? We love it too.
