Jessica Simpson sex tape?

It must be sex tape day....

Jessica Simpson reportedly reeling from the news that a sex tape starring her and ex-hubby Nick Lachey has hit the internet.

In the alleged X-rated home video, the 25-year-old star is said to be seen engrossed in various sexual acts with Lachey.

"Jessica is horrified her name and sex tape are being mentioned in the same sentence. She''s always been a girl of high morals and principles," Stuff.co.nz quoted a source, as telling Britain's Daily Sport newspaper.

Reports suggest that the tape does exist and has now landed in the hands of people who were behind making the Pamela Anderson and Tommy Lee sex video public.
