WWW- T.O. and porno? That’s a no-go, according to the Dallas Cowboy wideout’s lawyer.

An attorney for Terrell Owens dispatched a cease and desist letter to a hardcore pornography website, demanding they remove a picture of the smiling superstar from their page, according to TMZ.com.

The shot was taken when Owens apparently walked into an adult photo shoot taking place in Miami’s South Beach, TMZ reported.

The beaming Owens was unaware when the snapshot was taken that it would apppear on the web or link him to the adult entertainment industry, said the two-page letter from attorney Allan M. Lerner.

Owens was further aggravated by a picture caption reading, “What do you know, another football player who does not take his offseason seriously” – and the suggestion that he was pursuing a career in the porn business.

The angry legal missive from Lerner, obtained by TMZ, charged that TheDirty.com website was trying to “disrepute and smear” Owens’ reputation by posting the “misleading and nonconsensual” picture.

“We therefore demand that you immediately remove the photographs and the references from your website, state to your public that these photographs linking Mr. Owen to porn were not done with his consent,” the letter concluded.

The picture remained on the site this morning.
