If you're anything like us, you've probably wondered at some point how collaborations between pop stars come about.
Is it a purely business decision, decided in the boardroom by managers and label execs? Do musicians ever just bump into each other in the studio and hit it off?
And just how much planning and negotiation are involved before both parties finally get round to recording their tracks in the vocal booth?
Fortunately, Pink has shed a little bit of light on this subject, sharing a story in recent interviews about how she managed to get Eminem to appear on the track "Revenge" on her latest album Beautiful Trauma, and how it all began the same way so many other relationships do- with a drunken, rambling, overly-emotional email.
Speaking to Entertainment Weekly, Pink admitted that 'I sneak-attacked him'.
"Max [Martin] and I started making 'Revenge', and I wrote this rap. We were drinking a lot of wine, and then I went home and I thought more wine would be a good idea.
"I emailed [Eminem]. This is why they call it liquid courage. And I said, 'You know I love you. I like that you work with a lot of the same people, like Rihanna.
"She's hotter than me, but I'm funnier. So I'm going for a rap Grammy, and I'd like to take you along with me.' It was this long email, and he wrote back right away and just said, 'Okay'."
Ouch, that's cold. We've all had conversations stop dead in their tracks after spilling our guts out only to receive the dreaded 'k' in response, but to get one off Eminem himself must really sting.
Nevertheless, Pink didn't let the stony-faced response slow her down, and quickly fired off a response practically dripping with wine-mum energy.
"I emailed him again. I was like, 'This is the best thing I've ever heard! I want to tackle you and rub your face in the dirt!"
But apparently, the rapper replied yet again with another frosty 'Okay'.
Oof, strike two!
Despite Eminem's reluctance to partake in any online conversation though, they eventually did link up in the end, with Em sticking to his (single) word and laying down an admittedly pretty-strong feature on the track which makes up for his lack of correspondence.
Clearly, much like an ancient Kung-Fu master, Eminem only strikes out when it's absolutely necessary.Featured Image Credit: PA
