Kim Kardashian’s appearance in a Paper Magazine photo shoot in which she appeared naked has apparently led to a spike in sales of Kim K Superstar, the sex tape Kardashian had with former boyfriend Ray J, according to TMZ.

The tape is now the best-selling sex tape of all time, according to Steve Hirsch, president of Vivid Entertainment, which released the tape.

TMZ says that Ray J may have earned $50,000 last week from the sale of the tape and that the singer had been earning about $30,000 a month from the project.

In May, Ray J reportedly offered to give a portion of his sex tape profits to Kanye West and Kim Kardashian for their wedding.
