(Cover) - EN Showbiz - Kim Kardashian is apparently apathetic about her feud with Paris Hilton.

The reality star and her former best friend have not had a relationship for years and Kim is said to be disinterested when she hears news about the socialite.

RadarOnline claims that Kim is just focused on her continuing rise in the entertainment industry while Paris is reportedly peeved at how much more famous the Keeping Up With The Kardashians star is now.

"Kim couldn't care less about Paris, or what she thinks about her," a pal told the site.

"Bottom line, Kim used her friendship with Paris, straight up. She knows what she did and doesn't care. It's just like she's now using Kanye West to advance her agenda."

Meanwhile, Paris is set to relaunch her music career and is hoping her new album will get her back into the spotlight.

Although the hotel heiress is not as popular as she once was, she has continued to be very successful in her business endeavours with sought after perfume and handbag lines. (C) Cover Media
