Anyone who uses Twitter will know that Demi Moore is a big fan.

Not a day goes by when Mrs Kutcher isn't using her Twitter account to share inane comments or funny pics with her fans.

But it seems Demi also uses it to champion causes close to her heart, as Kim Kardashian found out to her disadvantage.

After the Kardashian sister posted a seemingly innocent photo of herself with celebrity friends La La Vazquez, Serena Williams and Kelly Rowland, with the caption "Big pimpin w @SerenajWilliams @LaLaVazquez @Kelly_Rowland Love u girls!", Kim felt the wrath of Demi.Kim Kardashian Kim Kardashian

Apparently Demi wasn't happy with Kim's choice of words and tweeted her, asking: "Are you using the word 'pimpin" as in pimping?" to which Kim replied: "Doesn't everyone? LOL." But Demi hit back saying "No disrespect I love a girls night out but a pimp and pimping is nothing more than a slave owner!"

As followers of both celebs tried to explain that Kim probably didn't mean any harm, Demi was quick to reveal her true issue, that we use words without thinking about their real meaning: "It's not her! we have allowed it 2 B considered cool, but it still is what its!"

Realising she'd caused a "s**t storm" with her comments, Demi softened the blow by adding, "Nothing wrong with dancing to Big Pimpin' by Jay-Z in the club! Having a girls night out, gotta love that song."
