Now that Amy Winehouse will be no longer hitched, will she become unhitched? That’s one question many will be asking as the self-proclaimed sober songstress is headed for divorce court.

After, British tabloids showed photos of Wino shacking up in St. Lucia with her 21-year-old boytoy, Josh Bowman, her husband is now looking to start divorce proceedings. A lawyer for her jailed husband said yesterday his client will be seeking a divorce on the grounds of the soul diva’s alleged infidelity.

Winehouse and Blake Fielder-Civil married in Miami in May 2007, but he was arrested six months later over an assault. In July he was sentenced to 27 months in jail for beating up a bar manager and then offering him a bribe to keep quiet about it.

Fielder-Civil was released into a drug rehab center in November but sent back to prison weeks later for breaching his bail conditions.

The romance between the two was tumultuous, with open drug use and violent public fights. During concert appearances last year, Amy often exhorted fans to call for the release of “my Blake.”

Can you blame her? She dumped a junkie for a hunkie rugby player —wouldn’t you?
