Mark Ronsonhas revealed that Amy Winehouse was "freaked out" byAdele's worldwide success.
The producer claims Amy felt "competitive" towards the Someone Like You singer after her sophomore album 21 broke records across the globe, but insisted the late star was still a fan of Adele and her music.
Speaking about Amy to The Village Voice, Ronson revealed: "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."
He added: "Anyway, we lost touch briefly. And before she and I could really start the process of beginning a new album, it was too late.''
