Jennifer Lopez's husband Marc Anthony has been embarrassed by a photo he posed for with a photographer charged with heroin possession and child pornography.

The candid snapshot, taken backstage at a New York concert Anthony headlined in 2004, is being used to prove the Latino singer had a relationship with photographer Michael Star, who is set to stand trial in the US after fleeing to Colombia.

The picture has been posted on Latino newspaper El Diario's website as part of a story suggesting Anthony was a friend of Star's.

But even Star's closest friends insist the photographer merely used Anthony's name and the photo to help him peddle his sick trade.

Rosa Sanabria admits the snapper used his so-called relationship with Anthony to lure young girls to his photo studio.

She tells the National Enquirer, "This guy is a monster and a sick person. It's awful for Marc to be dragged into this."

To make matters worse for the singer, Sanabria reveals Star will attempt to call Anthony to testify on his behalf when his trial comes to court.
