Paramore's Hayley Williams makes a special guest appearance in the video for rapper B.o.B's new single.

Williams also sings on 'Airplanes', which is released in the UK on August 9.

The song is already number two on the US iTunes chart – one place behind the rapper's last single 'Nothin' On You'.

Both songs appear on B.o.B's album, ‘B.o.B Presents: The Adventures Of Bobby Ray’, which is out now.
