Rap superstar Jay-Z will hand deliver his new album to bosses at Atlantic Records in London - as he is terrified of the unheard material being leaked on the internet.

The hip-hop legend's highly-anticipated new disc, Blueprint 3, is set for release on 11 September (09).But the Big Pimpin' hitmaker doesn't want to end up like stars such as Leona Lewis and Guns N' Roses, who have found their unreleased songs leaked online. A source tells Britain's Daily Star that Jay-Z decided the best way to stop this happening was to take the album to London himself.The source says, Every time a big artist has new music ready these days someone somewhere is always keen to pinch it and whack it on the internet. Jay is very protective and smart and doesn't want fans to hear tracks which aren't quite right. He wants to give the record to the label in the U.K. and see which songs go down best to give him ideas about single releases.Jay-Z arrives in London next week (beg20Jul09).
