Kim Kardashian has apologised for using the word 'retarded', calling her choice of word 'inappropriate and insensitive to the special needs community.'

The reality TV had used the word against her friends when they failed to recognise that she had dressed up as Pamela Anderson for a Halloween party - and the video had been posted on Instagram stories.

She told TMZ: ' want to apologize for what I said in a recent video post that is inappropriate and insensitive to the special needs community.

'I try to learn from my mistakes and this is one of those times. Please know that my intention is always pure, and in this case, it was a mistake. I’m sorry.'

Her shock slur comes months after her sister Khloe was forced to apologise for using the same word, while also using the story function on the photosharing site.

Kim put on a showstopping display for the spookiest evening of the year as she dressed as she transformed into the Nineties-inspired look.

The reality television star, 38, slipped her curves into a seductive lace corset and fuzzy pink hat to mirror Pam's look at the 1999 MTV Video Music Awards.

At her party Kim joked about how some of her younger friends wouldn't get the reference before making the slur. After sharing the look with pal Jaden Smith, she captioned the video: 'Too Young To Know WTF.'

In July, Khloe apologized for calling their sister Kourtney the word in her Instagram live stream. The 34-year-old took to Twitter to apologise on after fans called her out for calling her sister Kourtney 'a f*****g retard.'

The siblings were trying to set up an Instagram live stream of their exercise routine, but were having difficulty with the technical side.

Kourtney can be heard telling her younger sis 'Yes, you can you f*cking retard', while Khloe fires back 'are you a f*****g retard'.

'You should pay more attention to you word choices especially since you have a huge following & don't know who you could be offending,' one wrote.

While the reality star was seen solo on social media, Pam's original look was matched with then-hubby Tommy Lee dressed like a flasher

'If True had a disability you would use a different word.' But Khloe was quick to hold up her hand and accept responsibility.

The KUWTK star was immediately applauded for the way she handled the situation.

'Now this is the way you are accountable for your actions and apologize. Much respect to you for realizing what you said was wrong and owning up to it!' one wrote.

'It’s so difficult to break a habit like that but so much respect for really trying and owning up to mistakes,' another added.
