People and Hello! magazines spent millions of dollars for exclusive rights to the first images of Angelina Jolie and Brad Pitt's newborn daughter, only to have one of the images wind up on the Internet before either magazine was on sale.Tuesday, several blogs posted an image of the upcoming cover of the U.K.-based celebrity magazine Hello!, which shows the couple and their infant, Shiloh Nouvel. The photo is a vertical, close-up shot of the napping baby with the two parents looking down from above. "The biggest exclusive of the year," says the headline.Attorneys for People magazine promptly sent letters to blog owners asking them to delete the image. Hello! said it was cooperating with People in legal actions against those who published the photo.Responding to an e-mail from the Hollywood Bureau, Hello! features editor Juliet Herd confirmed the cover was authentic but said it was obtained illegally. The presence of a bar code on the image suggests that it may have been from late in the magazine's production cycle. Hello! goes on sale Thursday in Europe; People hits U.S. newsstands Friday.While some web sites pulled the image, it was proving difficult to put the toothpaste back in the tube.Getty Images is licensing the images on behalf of the family, with the proceeds to benefit unspecified charities. Getty says it will not profit from the sale. The prices People and Hello! paid for the photos were quickly leaked to The New York Post. In total, the photos could gross more than $10 million worldwide, widely believed to be the most ever paid for the rights to a photo shoot.People spent $4.1 million for rights to the photos after winning an auction over the weekend held at Getty's New York office, the Post's Page Six gossip column reported Tuesday. Hello! magazine won the U.K. rights for $3.5 million, according to a Post story Wednesday by media reporter Keith Kelly. The story also said People settled for the North American rights only after offering $5 million for exclusive worldwide rights.One bit of information that remains a mystery is who took the photograph."It was a Getty Images photographer," not a family member, Getty spokesperson Deb Trevino said Wednesday, but she said the shooter's identity was confidential.The photo agency kept security around the photos so tight that even Getty GEO Jonathan Klein said he had not seen the images."The reason I haven't seen them is because of the security around the pictures," Klein told CNN. "It's the first time we've done a major shoot where the only people who have seen the pictures are the photo editors and the sales people." Getty is letting Hello! and People handle the legal action around the Internet leaks, Trevino said.
