The STRIPPED star, 23, was reluctant to take on the job on Monday - but finally agreed after Al Fayed agreed to pay her $360,000 (GBP200,000) and lavish her with costly luxuries.
A source says, "Christina doesn't need to do any promotional work as she's probably the hottest singer around right now.
"Christina will be receiving $360,000 (GBP200,000) for her duties, which include cutting the ribbon, making a welcome speech and attending a VIP breakfast with Harrods executives.
"She'll be in London for two days but her official duties will take no more than two hours.
"She's requested that a private jet be sent to pick her up from her home in California.
"She has to stay in a penthouse - she doesn't really care where it is as long as it's five-star quality."
The American singer has also requested 10 bottles of room temperature mineral water and non-vintage Veuve Clicquot champagne.22/06/2004 15:17
