Whether she likes it or not, reality TV star Kim Kardashian owes much of her initial superstardom to a widely-distributed sex tape featuring her and her former boyfriend Ray J.

According to reports, rumors have surfaced of a second tape which includes more explicit footage of Kardashian and Ray J.

The Huffigton Post reports that the alleged “second tape — which is said to be much raunchier than Kim Kardashian Superstar — is now being shopped around to the tune of $30 million.”

“There is no truth to this and there’s no tape. Unfortunately the outlet that first wrote about this didn’t bother to check their sources or story,” Kardashian’s rep told Hollyscoop.

Meanwhile, Vivid, the adult entertainment company which retained the rights to the first sex tape, is weighing in.

“We’ve already spoken to the third party that brought the first tape to us and, a second tape, or additional footage from the first tape isn’t being shopped around or even exists,” Vivid Entertainment CEO Steve Hirsch Hirsch told TMZ.
