The reality TV favourite — famed for her voluptuous rear — this week launches her new fashion range in the UK.
Kim, 32, knows all too well how much pressure women can face to look good, and admits she’s had to learn to deal with so much attention being given to her shape.
She says: “I am really glad to be able to promote a healthy, natural body shape, eating well and exercising and appreciating the shape that you naturally have.
“I was a teenager in the 90s, which was the era of grunge, the waif and heroin chic.
“Female models were skeletal, and with my Armenian background that was a mould I was never going to fit.”
The range features more than 100 pieces in sizes 8 to 16, and is designed to make women of every size feel sexy.
Aside from her busy working schedule, Kim has been making headlines through her showbiz relationship with rapper Kanye West, 35.
Kim admits she has never been happier and said of the relationship in a recent interview: “We know what we are to each other.
“It’s so nice to have a best friend in this game who understands everything you’re going through.
“He’s been there through so many different stages of my life and before I was famous, so this relationship is a different thing entirely.
Despite her track record of failed relationships — including her infamous 72-day marriage to American basketball player Kris Humphries — Kim admits she still easily falls in love.
“I'll always believe the next one is ‘The One’, I’m such a hopeless romantic,” she says.
“It had always been my dream to have a big wedding. When people said that I’d made the wedding day over the top for the TV show, that was just me. I am over the top.
“But the next time I want to do it on an island with just my friends and family and that’s it.”
Despite having recently returned from a romantic trip to Italy with Kanye to celebrate her 32nd birthday, Kim says it is not overblown gestures but daily affection that counts.
“I don’t think romance is about one big thing, but about the way that someone treats you every day, and Kanye is very kind and thoughtful,” she explains.
And her idea of a perfect date? “I really like a guy who is confident, so I like a guy who has a plan for a date.
“There is nothing worse than a guy who shows up and just asks what I want to do.
“A really simple date of good food, and really good conversation with someone who I really have a spark with is perfect.”
Always open about her life and relationships, Kim has accumulated 16.5million followers on Twitter.
But despite her huge online fan base, she says she has a love-hate relationship with social media, which has been a breeding ground for online bullying against the star.
She admits: “Yes, I have been the subject of mean comments and nasty put-downs.
“I am confident enough in myself that I just ignore it. But what worries me is young people on social media who take these remarks to heart.
“I would like to say to them that the faceless bullies that target you are people who are just too weak to make a stand in the real world. Be confident in yourself, hold your head high and ignore them.
“If someone is really suffering, then I would say to definitely speak to a friend or a parent.
“My sister Khloé was bullied a lot when she was younger, so we now actively take a stand against bullying to help put a stop to it.
“It’s something we all feel very strongly about, and it’s important that our fans support us in trying to get people to be kinder to each other.”
