According to Hollywood Life on Monday, Kim is supposedly worried that Kylie is her "biggest competition" right now and is afraid that she might soon eclipse her as she is fast becoming the more popular sister in the family. Apparently, Kim is upset that Kylie has received numerous offers to become an adult film star and is begging her not to do it.

A source close to Kim and Kylie said, "Kim's so scared of Kylie catapulting into international fame that she's begging her NOT to do a sex tape. Kim doesn't want to be outdone. Kim's told Kylie she's 'already famous enough' and that 'doing a sex tape will ruin your soul.' Kim even went so far as to tell Kylie, 'If I could go back in time I wouldn't have made a sex tape with Ray J.'"

To make things worse, insiders say that Kim is secretly jealous of Kylie - who is looking more and more like her everyday - and that her rising popularity may jeopardize her celebrity career.

The source added, "Kim's worried that if Kylie were to make a sex tape with Tyga, not only would it earn more money than her tape with Ray J, it would catapult Kylie into a different stratosphere of fame and Kim doesn't want that. She doesn't want Kylie to be the biggest thing on earth right now."

So far, Kylie herself has not made any comments about the adult film offers.
