Kelly Osbourne is contractually obliged to have purple hair

Kelly Osbourne has to keep her hair purple for two years.

The 'Fashion Police' star admitted she would love to change her hair colour to green but was told she wouldn't be able to work if she dyed it a different shade.

She told E! News: 'I'm contracted to this hair colour. I can't change it for two years. I wanted to go green, but was told I wouldn't be able to work anymore.'

However, Kelly is happy with her hair and loves being called 'queen of the granny girls'.

She explained: 'In England, I'm called queen of the granny girls and I love it! My hair is a mix of gray, blue [and] lavender. It's hard to get this colour; you have to have blond hair to get the right shade.'

Fashion loving Kelly, 28, also revealed she has a number of Chanel hangbags at her home but never takes them outside.

She explained: 'I have Chanel handbags and I never wear them. I never wear them. I make music videos in my apartment with them. I don't want to ruin them. They make me happy.'
