The socialite and her siblings Kim and Kourtney recently launched their own pre-paid Mastercard, run a successful boutique and have an joint autobiography due for release, but admit their endeavours are part of a greater plan.

Khloe said: "I have plans to take over the world really soon. So in about six months, Kim is going to be the leader and Kourtney is going to rule her, and I will rule both of them."

Before they can take over the world, the sisters are preparing for the release of their book, `Kardashian Konfidential` - which hits shelves in the US on November 26, the day after Thanksgiving - and they can`t wait to launch their tome.

Kim told Us Weekly magazine: "It will be really exciting for our book to come out on Black Friday. That`s something that we worked a really long time for as well, and we?re anxious for it to come out."

Meanwhile, Kourtney has landed a part in a US soap opera.

The 31-year-old star - who has 11-month-old son Mason with boyfriend Scott Disick - is to make her acting debut in ?One Life to Live?.

Kourtney - who films scenes today (11.11.10) for an episode due to air in March - said: "I grew up watching `One Life to Live`. I hear I get into some trouble and I am looking forward to it. This may be my acting debut, but the Kardashians know a thing or two about drama."
