Apple has rejected a demand by Adele for hard copies of her upcoming album to be stocked in their stores.

Her agency William Morris Endeavour is reportedly in talks with Apple over the company's proposed sponsorship of her tour.

The asking price of £19.5m is around 10 times the size of a typical sponsorship deal for an artist of Adele's fame.

But as well as the huge payment, Adele's agent wants physical copies of her CD to be made available in Apple stores.

This is despite the fact that most Apple laptops don't have CD drives, and the company is one of the biggest sellers of digital music downloads.

Apple has reportedly refused.

The lead track from the upcoming album - called 25 - is called Hello and sits at number one in the charts.

The song's video also broke the Vevo record for the most views in a day with 27.7 million.

The album is out on 20 November, and is likely to be number one in 93 countries based on pre-order rates.

The report of the proposed tour sponsorship appeared in the New York Post.

Apple declined to comment.
