Kim Kardashian tweets excitement over fifth fragrance Pure Honey... but her brunette ad campaign is already out of date

It might be a new ad campaign, but judging by Kim Kardashian's dark locks, it already looks out of date.

If her brunette hair is anything to go by, Kim's latest campaign was shot before the birth of her daughter North West.

Interestingly the name of her new perfume is pure honey, the current shade Kim's new dye job.

The self-confessed workaholic tweeted a picture of her fragrance campaign on Monday, proving that there's no rest for the Kardashian sister.

'So excited to share that my fifth perfume, Pure Honey is here!' Kim wrote alongside the picture, that features an extreme close-up shot of the star.

Throughout Kim's pregnancy, the star was seen continuously on the go rarely taking a break, and it seems that having a baby certainly hasn't slowed down the wheels of her many business ventures.

Kim took to her blog to say: 'I wanted Pure Honey to be both light and sweet but also powerfully seductive. As women we all have these dual natures.'

'We can be girly and playful but also tempting and captivating at the same time. Combining the two elements was the perfect way to capture our full femininity.'

'I created it to be delectable and crave-able, like all beautiful women are.'

And like all celebrities who put their names to household products, Kim claims she did more than just give her signature to the final design.

'I am super involved from start to finish,' she claims.

'On bottle design to ad campaign. I had this really great honey idea, so we moved away from just florals. I wanted to make sure that it had the little bee on it.

It is Kim's fifth fragrance, which also include True Reflection, Glam, Gold and Signature.
