Dizzee Rascal wants to work with Calvin Harris again but he can't get in touch with him.
The pair teamed up on the rapper's hits 'Dance Wiv Me' and 'Holiday' and Dizzee admitted he is desperate to collaborate with the DJ again, but his pal is too busy at the moment.
He said: "I loved working with him but I can't get hold of him lately. If I could I'd be happy to collaborate with him again. I can't find him, he's all over the place right now."
Calvin's not the only artist Dizzee hopes to work with soon, with Kanye West at the top of his list of dream collaborators.
He told BANG Showbiz: "Kanye West is amazing, he's the one person that stands out for me right now but it's very difficult to choose."
However, in a perfect world, Dizzee - real name Dylan Mills - would team up with his deceased idols Bob Marley or Kurt Cobain.
He said: "If I could get Bob Marley on a track that would be wicked or Kurt Cobain or someone like that but there's no chance of that happening but it's such a hard question."
