Kim Kardashian Sex Tape Sales Surge After Pregnancy Announcement

Going back to what first made her famous

TMZ is reporting that Kim Kardashian's sex tape, the Vivid Entertainment video titled "Kim Kardashian: Superstar," has seen a dramatic spike in sales since the reality TV star and boyfriend singer Kanye Westannounced that they're expecting a babytogether. 

Apparently the sex tape has seen an 80% jump in sales since Sunday night, which is the biggest increase since Kim's 2011 marriage to NBA player Kris Humphries. Sales have been steadily rising since Kanye and Kim began dating last spring.
