Kelly Rowland and David Guetta say a studio session with Ne-Yo is a revelation.

The Destiny's Child singer and French star DJ hooked up to produce the Euro-pop track When Love Takes Over.

And they say they were stunned by Ne-Yo's studio style.

"He wrote the song in eight minutes. It's the fastest I've ever seen a songwriter write a song," said Kelly.

David added: "The track is eight minutes long, so I played the track and by the time it was finished, he was like 'turn on the mic, I'm ready'."
