JOE MANGANIELLO, FIANCEE SPLIT

Alcide is back on the prowl for a new she-wolf.

True Blood's Joe Mangeniello and fiancee Audra Marie have called it quits, multiple sources confirm to Us Weekly.

"It's totally over," one pal says.

Adds another insider: "It was a long time coming. They'll both be better off for it."

Manganiello's rep does not comment on his personal life.

After about a year and a half of dating, the hunky star, 34, and the model-actress announced their engagement in October 2010; he popped the question during a vacation in Italy.
