The singer, who recently revealed that her fortune is valued at about $20 million, threatened to leave Island Records after launching her next album, following a discussion with Alex Haines, reported FemaleFirst.
A source told The Sun, "For the first time in her career, Amy is beginning to have her head turned by the cash she can make. It’s never been a huge deal in the past, but she is beginning to realise everyone else is making money out of her success."
The record label has advised Winehouse to straighten herself out if she wants to launch another disc.
