Beyonce has worked with Diplo on a new track.

The producer and his former Major Lazer partner Switch produced 'Run the World (Girls)' - the first single from Beyonce's last album, '4'- and he has been back in the studio with her again, although it is not yet known if their collaboration will be on her forthcoming fifth record.

Diplo cryptically explained: ''I'm in the middle of something for her at the moment.''

Beyonce is not the only pop titan the producer - who rose to fame after producing 'Paper Planes' for M.I.A - has worked with, as he produced some songs on Justin Bieber's 2012 album 'Believe' and was impressed with the 19-year-old star's skills.

He said: ''The craziest thing about Justin Bieber is that the kid is crazily good at everything. He's really good at ping pong, the kid can rap, he has awesome hair, he's super cool and super nice.''

While he has teamed with some of the hottest names in music, Diplo's favourite person to have worked with recently is 'Boombastic' singer Shaggy.

He added to NME magazine: ''Shaggy's from the same place as me in Florida - Fort Lauderdale -and we have the same eclectic taste in music. He came to me as a fan wanting to get involved and we sort of instantly clicked. It was cool.''
