It is the premiere film festival in the world.

Shop till she pops: Angelina Jolie looks for baby clothes for her impending new arrivals

Yesterday, it was business as usual as the glamorous star, partner Brad Pitt, their daughter Shiloh and adopted son Maddox went shopping for children's clothes at upmarket boutique Bonpoint.

It was hardly a intimate outing, however, as they were accompanied by a mob of fans as well as the usual quota of paparazzi.

While crowds thronged around the outside of the small shop, Angelina, dressed in an strappy floor-length black dress and huge black sunglasses, spent an hour browsing the shelves and picking out clothes for Shiloh, who will be two later this month.

They eventually had to make their escape through wall-to-wall crowds thronging the boulevard outside the shop.

Hours later, the indefatigable Angelina was back out on the town for dinner, this time in a strapless dress which showed off her swelling cleavage.

She and Brad, 44, dined with veteran actor Clint Eastwood and Mick Jagger for dinner at Tetou.

Despite months of speculation that Angelina was pregnant with twins, she only confirmed the rumour earlier this week after an apparent gaff by Jack Black, her co-star in animated film Kung Fu Panda.

A day later Dustin Hoffman let slip the exact birth date - August 19.
