Rapper 50 Cent has denied reports he is working on Michael Jackson's comeback album - insisting the Thriller star doesn't need his help to make a hit record.

Jackson is said to have recruited some of the biggest names in hip-hop and R+B to collaborate with for his new disc, including the Black Eyed Peas' will.i.am, former Blackstreet frontman Teddy Riley and Akon.

But 50 Cent admits rumours of his involvement are all false.

He says, "It's not true. Anyway, what can you possible teach Michael Jackson about music? Nothing."
