Paris Hilton and Kim Kardashian were close friends back in the day when the hotel heiress was at the prime of her fame and when Kim was yet to have a reality show of her own. Rumor has it, the "Keeping Up With The Kardashians" star purportedly betrayed Paris and sold her secrets to tabloids back in the day.

According to Celeb Dirty Laundry, it may not be impossible that Kim Kardashian could be jealous of Paris Hilton's popularity back then.

"It all makes perfect sense. Kim was just Paris's closet cleaner until Kim found her own fame," Yellow J wrote in an article in the gossip website. "So why wouldn't Kim Kardashian be a little envious towards her socialite buddy Paris Hilton. We bet Kim would have done anything to get back at Paris and try to ruin her life."

Rumors claimed that Kim Kardashian reportedly made an effort to learn about Paris Hilton's skeletons in the closet and sold them to the press for big bucks, all while allegedly clinging to the hotel heiress to share the spotlight with her. These revelations triggered speculations that Kim might also be the one who have been feeding tabloids with stories about her family.

Despite rumors of betrayal, Paris Hilton doesn't seem to have any beef with her ex-stylist. "I'm so proud of Kim's success," Paris reportedly told Reveal.co.uk. "We've been friends ever since we were little girls and I always knew she'd go on to do big things. I couldn't be happier for her. I love to see people I've known my whole life doing so well."

Paris also only had good things to say about Kim and her marriage to Kanye West. "I think she and Kanye are perfect for each other," Paris added. "They're so in love, they have a beautiful daughter and they've been friends forever. They are truly a perfect match."
