Katie Holmes filed suit against the publishers of Star Magazine on Tuesday, accusing them of libel over a January magazine cover that implied she was a drug addict, according to The Associated Press.

In the lawsuit against American Media Inc., Holmes said the cover that featured the headline "Katie DRUG SHOCKER!" was not true and not supported by the story itself, according to the news agency. The story said Holmes was "trapped in a cycle of addictive treatments" and also implied that she is thinking of splitting from husband Tom Cruise, which the lawsuit also says is not true.

Star Magazine says it stands by its story, which doesn't refer to illicit drugs, but rather an alleged use of e-meters. An e-meter is a device used by Church of Scientology followers that practitioners say detects mental trauma. "Star fully stands behind the editorial integrity of what we have published concerning Ms. Holmes' controversial use of the Scientology 'e-meter,'" the magazine said in a statement. "Our attorneys look forward to deposing Ms. Holmes about her experiences with Scientology and the e-meter, and expect that the case will be promptly dismissed by the court."

"Star Magazine's malicious claims about Katie are untrue, unethical and unlawful," Holmes' attorney, Bert Fields, wrote in a statement. "Not only do they cruelly defame Katie, they play a cheap trick on the public, making ridiculously false claims on the cover unsupported by anything inside."

In her own statement, Holmes said the publisher knew the story was false "and printed it anyway to sell magazines."

Holmes is seeking more than $50 million in damages, claiming damage stemmed from those individuals who saw the cover, but never read the story to see that the allegations weren't about illicit drugs.
