A lawyer for Nick Lachey and Vanessa Minnillo is reportedly trying to keep photos of the pair having sex from being published. This week's Life + Style mag shows pics of the couple making out in a jacuzzi in Mexico, and according to TMZ, the photos only show half of their racy exploits. A source who has seen the pics (shot by paparazzi) claims the rest of the roll is "Paris sex-tape-level scandalous." Hollywood attorney Marty Singer has sent a letter of warning to all the weekly gossip mags, advising that if the pictures are published, they will face a hefty lawsuit. "The photos that were taken of our clients by a Mexican photographer violated Mexican law and were a clear invasion of privacy, and we have threatened to take legal action against third parties who publish the photos," Singer told TMZ, calling the photog "outrageous and malicious."source
