Eminem and Pink have a history. She was featured on his 2010 Recovery track 'Won't Back Down'.

Still, the 38-year old needed some liquid courage before she asked him to return the favor.

She explained to Entertainment Weekly how alcohol played a role in Eminem getting on her new track 'Revenge.'

“I sneak-attacked him,” Pink, 38, admits to EW. “[Producer] 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.” Finally ready, “I emailed [Eminem],” she continues. “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.'”
