Kim Kardashian going back to blonde?

Reality TV star Kim Kardashian says she is considering dying her hair platinum blonde again after her second child with her husband and rapper Kanye West is born.

When asked by a fan on micro-blogging website Twitter if she would go back to blonde this year, Kim said: "Not this year. I'm pregnant so can't. I loved it though so maybe in a year or two. it was so hard on my hair though.(sic)"

The 34-year-old beauty had earlier said that she had wanted to get her hair dyed platinum blonde for "a long time" after being inspired by Madonna.

"I've always had this image of Madonna with platinum hair in my references folder on my computer and I've been waiting a long time to try the look," she said.

However, she soon switched back to raven-coloured hair after struggling to keep her roots in check and was forced to head to the salon twice for touch ups in just 14 days.

Alongside a photograph of herself in the hair salon with blue bleach over her tresses, she wrote: "Being blonde is a full time job!"
