Cameron Diaz and one of her MTV reality show producers are suing the National Enquirer for $60 million for alleging they were romantically involved.

Attorneys for Diaz and "Trippin'" producer Shane Nickerson filed a joint lawsuit Wednesday in Los Angeles, accusing the tabloid of slander, libel and intentional and negligent infliction of emotional stress, "Celebrity Justice" reported.

The article last month claimed Diaz was cheating on her longtime partner Justin Timberlake, accompanied by 25 grainy photos under a headline "Cameron Caught Cheating."

The lawsuit claims the article not only damaged both of their reputations, but also placed needless strains on their personal relationships -- Diaz with Timberlake, and Nickerson with his wife and mother-in-law.

No comment from the Enquirer was available.
