While Kim Kardashian's infamous Paper magazine cover has generated mixed reactions, the celebutante is laughing all the way to the bank.

According to TMZ, Kim's nude pics sparked a renewed interest in her 2007 sex tape with Ray J.

Sources at Vivid Entertainment tell the gossip website that sales of the 'Kim K Superstar' video dramatically increased once the Paper magazine nude shots were unveiled. So much so, that Ray J will collect $50,000 just from last week's sales. There's no information on how much Kim is pocketing but it had to be triple the amount Ray J is getting since she's the leading star of the tape.

So far, the 'Love & Hip Hop Hollywood' star has been earning $90,000 every three months from the profits of the video.

Vivid Entertainment president Steve Hirsch has now proclaimed 'Kim K Superstar' as the biggest-selling celebrity sex tape of all time.

Not only is Kim Kardashian breaking the Internet, she's also breaking sales records in the adult entertainment business.
