Kim Kardashian drags her sister Kylie to court

According to the latest issue of Life & Style, however, this is not a joking matter to Kim. It's a very serious one. And it soon may be a legal one.

“Kim is fed up with how much money Kylie is making by mimicking her,” a totally real, definitely non-imaginary insider tells the tabloid, explaining that Kardashian thinks she’s “entitled to at least 30 percent" of Kylie’s earnings.

And, with Kylie's new website and app RAKING IN THE DOUGH, this 30 percent could equate to around $15 million over the next decade.

What is Kardashian's legal argument?

Kim think Jenner has “stolen her entire look, from head to toe, and is booking jobs that otherwise would’ve gone to Kim," this supposed source says.

It even goes so far as to claim Kim has “had her attorney draft papers [because] Kylie is essentially using her likeness without permission – so Kim has no problem suing her."
