Kelly osbourne is pretty passionate about purple

Kelly Osbourne's hair colour has changed from blonde to silver to lilac over the last few months, with the starlet settling on a vibrant violet shade for her latest transformation.

Showing off her new colour at a party in LA last night, Kelly's purple locks were styled in a high topknot - and matched with a purple dress and purple lipstick.

The combination of Kelly's updo and camera flash make it look as though she has a bit of a dip-dyed look going on, with lighter lilac ends graduating from deep purple roots - whether or not it's a trick of the light I'm not sure, but either way this shade looks pretty cool on Kelly.

The colour chameleon has worked her way through just about every colour imaginable over the years with style and panache - wonder what her next plan is?
