The "CSI: Miami" actor is seeking more than $1 million and an injunction from republishing the article's allegations. The story that ran in Life & Style's magazine and on its Web site earlier this month claimed Cibrian was having an affair with an aspiring actress.

An e-mail sent to the magazine's publicist was not immediately returned Thursday evening.

Cibrian's lawsuit states that he and the actress have both denied an affair.

Cibrian is divorcing his wife of eight years, Brandi. His relationship with Rimes has been tabloid fodder since they started dating after costarring in a television movie.
