Amy Winehouse has written a new song inspired by claims her husband is expecting a child with another woman, it’s been reported.

Blake Fielder-Civil is alleged to have made Gilleen Morris pregnant during a recent stint in rehab.

According to the Sun newspaper, Winehouse entered a recording studio in St Lucia just hours after hearing about the reports and wrote a “haunting” track, entitled ‘The Ultimate Betrayal’.

“Amy still felt they had something between them and that one day they’d be together again,” a source told the newspaper.

“But this news destroyed her.

“She sat down with her guitar and started writing ‘The Ultimate Betrayal’.

“She keeps repeating the line: ‘Blake a baby, no, no, no.’ It’s very haunting.”

Winehouse is understood to be on the Caribbean island in order to focus on recording her third album.

As previously reported, Fielder-Civil filed for divorce from Winehouse in January on grounds of her alleged infidelity.
