Kim Kardashian's unborn baby is already helping her cash in, but in a very unexpected way.
TMZ reports sales of the 32-year-old's sex tape, "Kim Kardashian Superstar," have skyrocketed since news broke that she and Kanye West are expecting their first child together.
Adult entertainment company Vivid Entertainment owns Kardashian's sex tape and told TMZ that video-on-demand purchases of the reality star's romp with then-boyfriend Ray J have spiked 80 percent since Sunday night .
According to the website, Kardashian's relationship with West (who also has his own sex tape floating around out there) has also been good for business, as the tape's overall sales have steadily increased each month since the two started dating in April.
It's not the first time that a big life event has bolstered the sales of the tape. When Kardashian said "I do" to Kris Humphries in August 2011, nearly 2 million people logged on during her wedding day weekend to watch her get it on.
TMZ also reports that Kim and Kanye have already decided their baby will never be featured on one of the family's reality shows, nor will there be a birth special (though we really doubt that Kim will keep her spawn from its reality TV destiny), but there's always the possibility a conception sex tape might "leak."
