Kim Kardashian's sex tape sales soar after baby news

Washington, Jan. 3 (ANI): Sales of Kim Kardashian's infamous sex tape have gone through the roof since her boyfriend Kanye West announced that the couple are expecting a baby.

Vivid Entertainment - that owns 'Kim K. Superstar' - said that the video-on-demand purchases of the sex tape have spiked 80 percent since Sunday night, TMZ.com reported.

It is the biggest increase that the tape has seen since the 32-year-old reality star married Kris Humphries.

According to the Sun, the socialite had sued distributors Vivid Entertainment for ownership of the 2003 tape - allegedly stolen during a house move - but dropped the suit in April 2007 and settled with the company for 3 million pounds. (ANI)
