Simpson sex-tape claims are false

Jessica Simpson's representative has dismissed reports of a sex tape featuring the star and her ex-husband Nick Lachey.

A British tabloid report earlier this week claimed the singer/actress, who is known for her clean-cut image, and Lachey had been caught in the act on explicit video footage.

However, Simpson's spokeswoman Lauren Auslander has refuted the allegations, telling website TheCelebrityTruth.com that there is "no truth" to the story because no such tape exists.

The former Newlyweds couple split in November 2005 after three years of marriage.
