Mark Ronson with Amy Winehouse

Amy Winehouse and Adele are probably two of the biggest voices to come out of the UK music scene, but Mark Ronson has revealed that the late singer had been ‘freaked out’ by Adele’s international success.

The 36-year-old music producer had been close to Amy for a number of years and claims that the huge fan base Adele’s 21 album gained, caused Amy to feel under pressure and she became competitive. He even implied that it might have been the reason the Valerie star was not herself in her final months.

Ronson told The Village Voice:

She was in a bad state, God knows why. I think that the Adele thing had Amy freaked out. She liked her, but Adele’s success was making Amy feel upset, competitive, restless. Anyway, we lost touch briefly. And before she and I could really start the process of beginning a new album, it was too late.

Adele’s sophomore album recently overtook Michael Jackson’s Thriller as the fifth best selling album in UK music history and is also the best selling album of the 21st century, pushing Amy’s Back to Black into second place.
