Former couple Kim Kardashian and Ray J are still reaping the rewards from their 2003 sex tape. Getty Images via John Shearer/WireImage Kim Kardashian's 2003 sex tape with her former boyfriend Ray J is now the biggest-selling sex tape of all time.

The title has been held by Pamela Anderson and Tommy Lee since 1995 for their home video.

Kardashian dethroned Anderson thanks to renewed interest after her nude Paper magazine spread last week.

According to TMZ, her sex tape sales have since increased exponentially.

While the site reports Ray J usually earns $90,000 every three months from his deal with Vivid Entertainment, the 33-year-old will rake in $50,000 from the past week alone.

Vivid Entertainment president Steve Hirsch tells TMZ that those sales pushed the sex tape rankings over the edge for "Kim K: Superstar."

Kardashian reportedly received $5 million from Vivid, giving the company the rights to distribute the sex tape, back in 2007. Today, the 34-year-old reality star is reportedly worth more than $65 million.

Ray J, a rapper-actor-music producer, is worth a reported $6 million.
