Skrillex - Sparks Fly In Studio For Skrillex And Goulding

The couple found love last year (11) after exchanging a series of emails and meeting up for the first time in Tennessee.

Now they have taken their relationship to the next level by collaborating on a track with producers Steve Angello and Sebastian Ingrosso of Swedish House Mafia.

Ingrosso tells Billboard.com, "We made a demo and it was amazing; we had a blast. Ellie is a great artist... her voice is amazing. Skrillex, enough said, he is Skrillex...

"Ellie and Skrillex came in 30 minutes late, and we had already started with a melody. Skrillex freaked out, he loved it, and after a few hours we wrote the song."

Ingrosso admits there are no definite plans to put out the song, but hopes it will feature on Goulding's next release.

He adds, "I think it's going to be for (Goulding's) album, but in this business you don't know until you see it on (digital music retailer) iTunes."
