Just weeks before her rumoured wedding to Kris Humphries, Kim Kardashian has been experimenting with hair colour and has decided to go a few shades lighter.

The 'Keeping Up With The Kardashians' star was seen in Studio City, California yesterday after filming for the familys' reality series with a distinctly lighter look

Kardashian, has gone from her usual almost jet-black locks for a dark brown, which she has experimented with in the past. Kim has been organising her wedding since the couple announced their engagement just a few weeks ago, and has been spotted at Vera Wang's flagship store in New York, presumably choosing her wedding gown.

The reality star is also getting herself in tip-top shape by working out intensely ahead of the big day. Yesterday she tweeted: "Morning GORGEOUS!!!! Just finished an intense workout! I am so much more on my grind when I am in LA!"

Kardashian has also hired Jennifer Lopez's coach Gunnar Peterson and Gwyneth Paltrow favourite Tracy Anderson to help her reach her goals.

Anderson recently told Life & Style magazine: "We don’t want to take away Kim’s amazing curves, so we just do specific movements to tighten the skin and to pull the muscles tight against the bone."

What do you think of Kim Kardashian's new hairstyle?
