AMY WINEHOUSE has applied for permission to visit her jailed husband in a desperate final attempt to save their marriage.

Blake Fielder-Civil, jailed in the U.K. for causing actual bodily harm and perverting the course of justice, filed for divorce earlier this month in a bid to bring the couple's 20-month union to an end.

But the Back To Black singer - currently on a a sunshine break in the Caribbean - has subsequently vowed to salvage their relationship, and her marriage.

And now the star has reportedly made plans to fly back to Britain and visit her spouse in prison, in a bid to persuade him to change his mind about the divorce.

A source tells British newspaper The Sun, "Since he began divorce proceedings, Amy has decided she wants to try and work things out.

"She has applied to visit him in jail in Britain and if he accepts she will fly back. We will see what is his priority - Amy or her money."

Amy married Blake in Miami, Florida in 2007.
