Paris Hilton is apparently fuming with Kim Kardashian – because her ex BFF has stolen the limelight.

According to Page Six, the sassy blonde is mad that the reality star and her sisters are getting all of the fame and fortune she’s grown acustomed to.

“Paris is furious that Kim got her start by hanging out in Hollywood with her — and now, the Kardashians have it all, the reality shows, the magazine covers, the big appearance fees and promotional deals,” a source alleges.

“She used to command $100,000 for club appearances, but now Kim is the hottest girl — and they aren’t friends anymore.

“The magazines are bidding around $300,000 for Kourtney’s baby-shower and baby pictures. And Khloe’s wedding brought in record ratings for E!

“Paris has realized that standing for excess in a recession doesn’t appeal.

“The Kardashian girls seem more real, and girls identify with them more. She’s got to ditch the pink Bentley and concentrate on developing herself.

“Paris has 15 product lines on sale. She isn’t really a party girl anymore, she is quite settled with boyfriend Doug Reinhardt.

“She wants more people to appreciate that she’s grown up.”
