Eminem And Paramore's Hayley Williams' Duet Leaks Online

A new track featuring Eminem and Paramore singer Hayley Williams has appeared online.

The song, entitled 'Airplanes (Patt II)', is one of a number of collaborations on Atlanta rapper B.O.B's new album, 'The Adventures Of Bobby Ray'.

Williams kicks starts the song before B.O.B takes over for the second verse. Eminem then closes the track.

Earlier this month, Williams revealed that she featured on two songs on the album but only recently discovered that one of them also featured Eminem.

“He just slays me, he's such a genius,” she said of the rapper.

'The Adventures Of Bobby Ray' is due to be released on April 27.
