NFL star, malcontent and Tony Romo teammate Terrell Owens is bitching that he's no porn star, despite a picture of him allegedly walking onto the set of an adult film, as depicted on a hard core adult website.

The photo shows the Dallas Cowboys wide receiver strolling into an adult photo shoot with a huge smile on his face. The shot somehow wound up on TheDirty.com, with the clever headline "T.O. Loves Porn."

Terrell Owens? Not thrilled about this development. He immediately dispatched his legal team to clean up the mess, an the story no longer appears.

A cease and desist letter was sent to TheDirty.com explaining that Terrell Owens "unknowingly walked into" the sticky situation. Mmm hmm.

Lawyers for the crybaby football star demanded the site take down the pics of Terrell and implicitly "state to the public that these photographs linking Mr. Owens to porn were not done with his consent."

As much as it sounds absurd that he could walk onto the set of a porno by mistake, we must keep in mind that this took place in South Beach.

Maybe he's telling the truth ... and we need a Florida vacation about now.
