Kim Kardashian West insists there is no rivalry between her and Jennifer Lopez.

The 'Keeping Up with the Kardashians' star - who posted a photograph of herself on Instagram posing alongside the 'Booty' hitmaker with their backs to the camera at the Met Gala 2015 on Monday night (04.05.15), which was quickly dubbed the ''Battle of the Booties'' on Twitter - says the 45-year-old actress was her ''idol'' when she was younger.

The 34-year-old beauty said: ''I don't think [it was a battle]. [Jennifer] was my idol. She's so beautiful. It was fun hanging out with her.''

Meanwhile, Kim admits some of her family members are still coming to terms with her stepfather Bruce Jenner's transition from male to female.

Speaking to about the upcoming E! special in which he discusses the changes in his life with his children, she said: ''Every family member gets really emotional. And you'll see moments - I think that's why we really, really wanted to do this special, because other families are definitely going through what we're going through. And every family member has a different reaction, and that's OK.

''At the end of the day, we all support Bruce, no matter what. But there's a journey that you have to go on to understand it. That journey is different for everybody.''
