Miley Cyrus and Kanye West's collaboration is ''sounding crazy''.

The 'We Can't Stop' singer recorded vocals with Kanye for a remix of his track 'Blkkk Skkkn Head' and producer Mike Will says they make a formidable team.

He said: ''It's about done, we're just touching the beat up a little bit. It's sounding crazy.''

Mike also said he's sure Kanye is supportive of Miley's controversial twerking routine at the MTV Video Music Awards (VMAs) last month, which outraged many people when she writhed around Robin Thicke in a flesh coloured latex bikini and danced suggestively with a foam finger.

Speaking on to MTV's RapFix Live, Mike said: ''He told her she did it right. Kanye is someone who understands. I think someone who understands isn't going to have anything to say about the performance.''

Miley was said to have gone to the studio with Kanye as soon as the MTV VMAs had finished, even missing her own after party to work on the ''top secret'' remix.
