"Die With A Smile" is a soul-rock duet between Lady Gaga and Bruno Mars. The song finds the pair realizing how much they mean to each other - a lot! They're both willing to die in each other's arms.

Bruno kicks things off by recounting a bad dream where he had to say goodbye to Gaga only to wake up with the sudden gut-punch realization of just how much she means to him. It's the kind of epiphany that makes you want to hold someone close and never let go. Then Gaga swoops in for the second verse, adding her own layer to this melodramatic love tale. She reveals that the couple has been through the wringer, fighting and losing sight of what they have together. From there, the two bounce off each other's vocals with all the chemistry of a well-matched tennis pair, belting out their renewed commitment to one another in a way that makes you believe true love really does conquer all, or at least makes for one heck of a duet.

The collaboration was the first time the two pop titans have worked together. It all began when Mars, tinkering away in his studio on some new material, decided to extend an invitation to Gaga. "Bruno and I have a lot of mutual respect for each other," Gaga explained. "We'd been talking about collaborating for a while. I was wrapping up my own album in Malibu when, after a long day, he called me over to his studio to listen to something he'd been working on." Gaga arrived around midnight, that magical hour when creativity either collapses in a heap or soars into the stratosphere. When she heard what Mars had been cooking up, she was blown away. "We stayed up all night," she said, "and finished writing and recording the song."
