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.
At the time, Manganiello gushed to E! News of his love: "I always dreamed of finding someone who is beautiful and sweet, equal parts. And I did. From there she's just unbelievably understanding and compassionate and patient from all the craziness that comes from this job and lifestyle."
But by spring 2011, a source close to the actor noted he "refused" to set a wedding date. "He [went] completely quiet about discussing wedding details," the source said.
As his then bride-to-be forged ahead with choosing her wedding dress, her bridal party and even her gift registry, "He [was] clearly having reservations."
Manganellio hasn't exactly gone into hiding in the wake of the split. On Monday Sept. 12, he hit the W Hotels' Fashion Next bash for Mercedes Benz Fashion Week -- where he and actress Rose McGowan sat and chatted together for a while and sipped champagne.
"I was surprised how long they chatted for," an onlooker says.
