A New Jersey middle school accidentally sent a racy picture of a model wearing a bra to students in what was meant to be a pajama party invitation, MyFoxPhilly.com reports. 

The principal at Pitman Memorial Middle School said his secretary searched the Internet for the image of a child with slippers and a teddy bear for the flyer -- sent to students in an email -- but a picture of Victoria's Secret model Adriana Lima was secretly tagged in it as well, according to the station. 

The owner of the picture reportedly used a hitchhiker virus, which was embedded in the innocent host image. Websites sometimes add hitchhiker viruses to prevent people from stealing their content. 

The principal immediately sent out a message to parents apologizing for the mistake.
