Porn company boss says a Kylie Jenner sex tape could be bigger than Kim Kardashian's

Several companies have reportedly been in touch with offers ranging from six to seven figures

Kylie Jenner celebrated her 18th birthday earlier this month and has reportedly already been inundated with offers from porn companies.

The Keeping Up With The Kardashians star is said to have been contacted by a number of brands wanting to be the one to release a sex tape.

The boss of Vivid Entertainment - who were behind Kim Kardashian's infamous sex tape with boyfriend at the time Ray J - has said a Kylie Jenner video could outdo her big sister's, which netted tens of millions of dollars.

No wonder Vivid Entertainment boss Steve Hirsch has made an incredible $10MILLION offer for her and Tyga to get intimate in front of a camera then.

According to TMZ, Steve is said to have written: "Kim's sex tape helped launch her career and would be nothing but positive for you."

They face competition from BangYouLater, who reportedly proposed: "This event will make you even more famous than either Kim K or Paris Hilton."

However, they have put down a marker for the hypothetical romp, insisting the scene "must be at least 22 minutes in length".

Meanwhile, Digital Playground have made Kylie a couple of offers, apparently - to become a "Brand Ambassador" or a star herself.

According to reports, they wrote to her saying: Now that you are of legal age, we would like to offer you the opportunity to be Digital Playground's Brand Ambassador!"

They continued: "We know you'll be great at this and with your banging body to match, maybe you'll be interested in becoming an adult star yourself!"

If she did actually accept an offer it would see her almost following in Kim's footsteps after she made headlines in 2007 when her infamous video with former boyfriend Ray J was leaked online.
