Amy Winehouse Amy Winehouse

Amy Winehouse's husband, Blake Civil-Fielder, has begun divorce proceedings against the troubled singer, People reports.

"I can confirm that I have been instructed to commence divorce proceedings on the grounds of Amy's adultery," Henri Brandman, a lawyer for Civil-Fielder, said in a statement.

In recent weeks, Winehouse has been spotted cavorting with 21-year-old rugby player, Josh Bowman, telling News of the World in a candid interview that she's finally sobered up and "in love again."

Civil-Fielder, who spent almost a year in jail for assault ("My Blake, my Blake incarcerated!"), first spoke of ending his marriage to the 25-year-old in November. "I have to let her go to save her life," he said at the time.

The two have been married since May 2007.
