When Will We See the Jolie-Pitt Babies' Faces?

At 2 days old, Knox Leon and Vivienne Marcheline Jolie-Pitt are the newest, hottest superduo on Hollywood's radar.

Power couple Angelina Jolie, 33, and Brad Pitt, 44, welcomed the boy and girl twins, their fifth and sixth children, Saturday night at Fondation Lenval Hospital in Nice, France.

The twins' arrival marks the latest in the frenzy surrounding celebrity offspring and will kick off a turbocharged race for the first photographs of the children.

While celebrity baby photos are "all in demand," the Jolie-Pitt newborns are on another level on the celebrity stratosphere, says Jess Cagle, executive editor of People magazine. "I've never seen an interest in any babies like this before. The thing that sets these babies apart from other celebrity births is there's a level of curiosity about Brad and Angelina that doesn't exist for other celebrities. These twins are really the perfect storm: beautiful, glamorous parents, a multiple birth, a media frenzy with a nine-month build-up."

The first photos of Jolie and Pitt's daughter Shiloh, 2, went to People for an unconfirmed sum and were published weeks after her birth in May 2006. Celebrities usually set up photo deals soon after their babies are born, often to deter paparazzi from trying to get their own exclusive glimpses.

"Maybe it does devalue the (paparazzi) photos … but I don't think it stops photographers from violating their space," says publicist Ken Sunshine, whose clients include Ben Affleck and Jennifer Garner.

Publications usually stay mum about claiming rights to the first baby photos and the amount of money it took to seal the deal. So far, no deal has been confirmed, but photos of the twins could bring in a record-breaking figure of many millions.

Among details that emerged Sunday:

•The names: Vivienne Marcheline is most likely named after Jolie's mother, actress Marcheline Bertrand, who died of cancer in 2007. Knox Leon's name is more in sync with those of his siblings: Maddox, 6, Pax, 4, Zahara, 3, and Shiloh.

•The delivery: Pitt was by Jolie's side for the birth and cut the babies' umbilical cords. Jolie "was awake and speaking and laughing. They were happy," said Michel Sussmann, the obstetrician who delivered the babies by Cesarean section, a common procedure for multiples. About half of twins are born at low birth weights, less than 5½ pounds. Knox Leon was just over 5 pounds, and Vivienne Marcheline, who followed a minute later, was 5 pounds. Contributing: Liz Szabo
