Amy Winehouse felt "competitive" towards Adele.

The "Rehab" singer - who passed away from accidental alcohol poisoning last year - was ''freaked out'' by the worldwide acclaim "Someone Like You" hitmaker Adele received, according to their mutual friend Mark Ronson. "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," he said.
