Troubled British singer Amy Winehouse reportedly rejected every song that rocker Pete Doherty wrote for their collaborative album.

Doherty, who just got out of jail, and Winehouse are having trouble working together since Winehouse is adamant and stubborn in the recording studio, reports ananova.com.

An inside source said: “Amy has thrown back every song Pete has written for her. She keeps telling him it’s rubbish and worse—and she’ll only perform if the song is great.

“When she’s in the studio she can be ruthless and she doesn’t care about hurting people. Pete’s struggling to get it together, it hasn’t clicked yet.”
