12. Toddla T and Annie Mac
Radio One's dance music crusaders, Annie Mac and Toddla T have been an item for quite some time and solidified their relationship when they announced that they were expecting their first child last year. The little one is set to arrive in May 2013 and will be headlining the 'Annie Mac Presents' tour in 2036.
11. The Long Lost
Alfred Darlington is best known as Daedalus, one of the founding fathers of the LA beat scene, but he also finds time to make lo-fi folk with his wife Laura. The two were even partners in their high school ballroom dancing club. Talk about dance credentials.
10. DJ A-Trak and Kid Sister
Melisa Young was a relative unknown when she dropped 'Pro Nails' in 2007. The frat-party anthem went on to garner a Kanye West remix, a record deal with Fools Gold and even a boyfriend in the form of label boss Alain Macklovitch. Some people get all the luck.
9. Peaking Lights
Not only have married couple Indra Dunis and Aaron Coyes produced three LPs of the finest psychedelic dub, they've also produced a child, Mikko, who they take on tour. Their track 'Beautiful Son' is named after him, presumably as a cheaper alternative to buying a birthday gift.
8. Diplo and Mia
Like all the best relationships, this began in Fabric, when MIA heard the Mad Decent manager playing her single 'Galang'. The couple collaborated on her first two albums, before splitting up soon after MIA's breakthrough with 'Paper Planes'.
7. Beyoncé and Jay-Z
A match made in hip hop heaven, the union of the certified king and queen of urban music seems inevitable with hindsight. With their combined assets, daughter Blue Ivy Carter looks set to inherit the GDP of a small country. Crazi In Love indeed.
"Do you like my tight sweater? See how it fits my body!" Best not try this chat-up line in your local Wetherspoon's, but it bagged Róisín Murphy a date with Moloko cohort and future boyfriend Mary Brydon. In fact, it worked so well they used it as the title for their first album.
5. Judge Jules and Amanda O'Riordan
Jules and his wife have worked together in the group Angelic, and she's also laid down vocals on some of his solo productions. This may make them sound like trance's answer to John and Yoko, but luckily the tunes are pretty good.
4. Everything But The Girl
The name seems a tad strange when you realise that Buzzin' Fly boss Ben Watt got the girl way back in 1982, when he met fellow Hull Uni student Tracey Thorn. They had a string of pop and dance hits before semi-retiring the EBTG monkier to raise their two children. Aw.
3. Goldie and Björk
The weirdest pairing on this list. The decision by the jungle veteran and the icelandic eccentric not to hook up in the studio has led to one of the great 'what ifs' of dance music: would it have been another 'Timeless? Or just 'It's Oh So Quiet' with added Amen breaks?
2. Madonna and Jellybean Benitez
With her recent ill-advised references to 'Molly' it's easy to forget Madge was around during club culture's formative years. Back in the 80s, Madonna's hook-up with NYC DJ and producer Benitez coincided with arguably her greatest work.
And the winner is...
1. David and Cathy Guetta
Forget Snoop, Rihanna and Nicki Minaj; the floppy haired chart-topper's most successful collaboration to date is still his marriage to club-owning socialite Cathy. Describing herself as a "mum and businesswoman" by day and "party person" by night, the mother of two still finds time to helm their insanely popular F*** Me I'm Famous! parties at Pacha. In fact, the couple love the White Isle so much they renewed their wedding vows there this summer in the presence of Oakie, Tong and Afrojack.
