Kim Kardashian has branded her former stepmother a "slippery snake."

The Keeping Up with the Kardashians star, her siblings and mother Kris Jenner have filed a lawsuit against Ellen Pearson - the former wife of her late father Robert Kardashian - claiming she sold personal property, including family photos, to a publication in January 2013 and in her deposition, Kim admitted she "disliked" her.

When asked her opinion of Ellen - who married Robert six weeks before he died in 2003 - Kim said, "She is a slippery snake... I dislike her. I think that she -- I don't agree with her decisions as of late. And I didn't agree with her decisions when she wouldn't give us back property or ever since she married my father, I haven't agreed with her decisions. I feel like there was an agenda there -- but I don't think about Ellen. I don't spend my time worrying about her, because I try to be a positive person. Everyone is pushed to a limit, and no matter how positive you are, you can look at someone and say, wow, they are a slippery snake, they make awful decisions that are hurtful."

And her sister Khloe admitted she and her siblings Kim, Khloe and Rob, were against Ellen's marriage to Robert, who died of cancer aged 59. According to RadarOnline.com, in her deposition, she said, "We just didn't feel like she was a good fit for my dad. They would fight a lot, and they would break up all the time. [Were we all on the same page?] That they should not be getting married, yes."

The family are seeking $500,000 in damages, in addition to profits, statutory damages, punitive and exemplary damages.
