JAY-Z will reportedly deliver his new album to his record label in person to try and stop internet leaks.
The hip-hop star said he is ready to share The Blueprint 3 with bosses at Atlantic Records after spending recent months hard at work on it.
A source revealed: "Jay is looking forward to showing off the fruits of his studio time and decided the best thing to do was take the album himself to London.
"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 UK and see which songs go down best to give him ideas about single releases."
