Sienna Miller is pulling a Demi Moore and taking a 16 year as her date to her UK premiere of her long awaited flick "Factory Girl...well sort of. The 24-year-old actress will accompany a lucky teenager to her movie premiere after the teenster paid £2,000 for the date at an auction.

After the event, Sienna and her date will enjoy a candle-lit dinner at London's exclusive Paper restaurant. The date is for a good cause, as the auction raised funds for Unicef's Unite For Children Against AIDS campaign.

A Unicef source said: "He is a very charming young man. I'm sure they'll have a great time, she's thrilled." Sienna's adolescent date apparently worked five jobs to raise enough money to bid for the rendezvous. Despite his best efforts he did not raise enough cash and, as the bids kept going up, he was kindly offered the outstanding £600 he needed by a fellow guest - an Indian prince. That's pretty cute, huh?
