Paris, Jul 14: They are the ultimate million-dollar babes.

Angelina Jolie and Brad Pitt's new twins, a girl and a boy born by Caesarean section on Saturday, are barely a few hours old but already their first photos are worth a fortune.

A million dollars, two, five, 10 even 20 million? Exactly how much the first ''official'' snaps will be sold for is not clear. But the figures being bandied about make the eyes pop.

Nice Matin, the hometown daily in the Riviera city in the south of France where Jolie gave birth, put the twins' worth at more than US$11 million. It first broke news of the birth and reported Sunday that the couple have sold the rights for the first photo of their newly enlarged family to a US publication, which it did not name, and that the proceeds would go to charity.

''I've never known a set of pictures to be worth this amount of money,'' said Darryn Lyons, owner of Big Pictures, a celebrity photo agency in London. He estimated that the twins' official photos will be worth between US$15 million and US$20 million.

The only other photos that ''would possibly come that close is Britney Spears giving birth to an alien,'' he said.

Veteran London-based celebrity publicist Max Clifford estimated that the first photos could fetch 10 million pounds - roughly $20 million, ''which would make it the biggest baby deal ever.''

''These kind of pictures sell lots of magazines,'' he said. ''It's a 10-million-pound (US$20 million) gamble as to whether the ends justify the means. But obviously it's a very calculated risk because whoever lands the photos will have a lot of experience with the popularity of mum and dad.''

Cue the paparazzi. They've been camped in Nice since shortly after Jolie's admission to the Lenval hospital there at the end of June, hoping for possibly lucrative pictures of the glamourous Hollywood couple. For them, the Brangelina twins are the biggest story of the year.
