The 7 most bizarre, unexpected rapper and singer collaborations ever

Yes, these actually happened

Busta Rhymes ft Ozzy Osbourne - 'This Means War': Featuring a rather lazy sample of Black Sabbath's 'Iron Man', this bizarre 1998 collaboration between the Brooklyn rapper and Sabbath frontman Osbourne is best forgotten.

DMX featuring Marilyn Manson - 'The Omen': The New York rapper and controversial goth shock-rocker Marilyn Manson teamed up for this extremely creepy track in 1998. DMX's raw, aggressive vocals and Manson's own unsettling tones make it an uneasy listen.

Eminem ft Dido - 'Stan': Possibly the most famous and successful unlikely collaboration of them all, meek mum's favourite Dido lent her vocals to Eminem's bleak, hard-hitting hit 'Stan', which topped the charts in the December of 2000.

Tupac ft Elton John - 'Ghetto Gospel': A Tupac song featuring an Elton John sample shouldn't work, but it did. Elton's chorus from his track 'Indian Sunset' worked brilliantly with Tupac's socially conscious lyrics, and it was a big posthumous hit for the rapper in 2005. Elton is an unlikely favourite of the rap world - he also duetted live with Eminem.

The Jonas Brothers ft Common - 'Don't Charge Me For the Crime': Possibly the most bizarre entry on this list, Disney teen-boppers the Jonas Brothers enlisted credible, deep-thinking rapper Common for this weird, faux-attitude packed rock track, featuring squealing guitar riffs and Common sounding like he doesn't know how the hell he ended up on the track in the first place.

Wale ft Lady Gaga - 'Chillin'': In 2009, Wale was a rising rapper and Gaga a rising singer, so it made sense for them to collaborate and raise their profiles. 'Chillin'' is actually a great track, and was a hit in the UK. Considering the status of both Wale's and Gaga's respective careers now, it seems strange this ever happened.

Wu-Tang Clan ft Cher - TBC: The leotard-loving, wig-rocking Queen of auto tune is set to feature on the pioneering rap collective's one of a kind album, Once Upon A Time In Shaolin. We truly didn't see this one coming, but we're very glad it's happening.

It's been confirmed that Cher, the ACTUAL Cher, will be appearing on Wu-Tang Clan's forthcoming, one of a kind album and it may be the weirdest collaboration news we've heard in a while.

It's not the only unexpected, bizarre rap/sung duet to occur, however. There's a host of unlikely pairings who have teamed up in the past - with wildly varying results. From Busta Rhymes and Ozzy Osbourne, to Tupac and Elton John, here are weirdest rap/sung collaborations ever.
