Jessica Alba has threatened Playboy lothario Hugh Hefner with legal action, insisting the March issue of his magazine suggests she poses "nude or semi-nude." The beauty shot off a legal warning to the magazine mogul after realizing her image had been placed on the cover of the soft-porn publication without her knowledge or consent.

The letter demands Playboy immediately stops distributing the offending issue, and Alba insists a "monetary settlement" is appropriate. Alba's lawyer Brian Wolf claims the actress had previously turned down a substantial payment to be a Playboy covergirl and accuses the publication of tricking Colombia Pictures into allowing them a promotional shot from forthcoming film Into The Blue.

Colombia Pictures have also written to Hefner, slamming the "outrageous, unethical behavior utilized by Playboy personnel to obtain" the racy shot.
