Rapper Jay Z intends to make One Direction member Harry Styles `the biggest artiste in the world`.

Jay Z, who has mentored the likes of Rihanna, Shakira and Kanye West, has vowed to give Styles the help he needs to forge a solo career, reports mirror.co.uk.

"Harry doesn't need any help with exposure, everybody in the world knows who he is,` Jay Z told The Daily Star Sunday.

"But he does need to make the transition from being part of a group to becoming an individual artiste. I can get him working with the bigger artistes, the biggest producers - and have him as the biggest artiste in the world within a year,` he added.

Styles, 21, who was in news for being spotted kissing Kendall Jenner, has been working hard on his solo material and even registered new songs with the American Society of Composers, Authors and Publishers.
