London - Kourtney Kardashian claims her sister Kim causes drama in their family.

The 33-year-old reality TV star - who has two children, Mason, 3, and seven-month-old Penelope with her long-term boyfriend Scott Disick - says her younger sister has a habit of creating problems for them but insists they usually get on “really well”.

The Keeping Up With The Kardashians star told “Kim is a drama causer,” explaining that her younger sister invited her boyfriend Scott to go to Miami, Florida, with them behind her back.

Kim, who is expecting her first child in June with boyfriend Kanye West, admitted that she has caused a lot of arguments among her friends and family, especially while filming the new season of their spin-off reality series Kourtney & Kim Take Miami.

She said: “This season, I took a look back and I realised how much in everyone's business I really was, and how nosy I was - to the point that I was causing people to get into, like, physical fights, crying, leaving, storming out.”

But she also hit back at her sister's comment, insisting she only gets involved in other people's business with “the best intentions” of helping them resolve any issues.

She said: “Everyone was having issues, and I was always trying to bring people together and just make it better.”

Kim has also revealed that her rapper beau Kanye won't feature in the new E! series because he was recording his new album in Europe while she was filming the show.
