It's over for Charlie Sheen and his former porn star fiancée.

The actor, 49, announced his breakup with Brett Rossi, whose real name is Scottine Ross, just week before their November wedding.

"Scotty and I had a great year together as we traveled the world and crossed a lot of things off our bucket list. She's a terrific gal - but we've mutually decided to go our separate ways and not spend the rest of our lives together," he said in a statement to E! News.

"I've decided that my children deserve my focus more than a relationship does right now," Sheen said about his five children. "I still have a tremendous fondness for Scotty and I wish her all the best."

The couple, who first went public with their relationship last November, got engaged in February during a romantic Valentine's Day trip to Hawaii.

"Yes! We are engaged! He even was a gentleman and got down on one knee," she told the publication at the time. "I was not expecting it at all. We had a beautiful Valentine's Day and he proposed to me early this morning after we watched the sun rise.

"The ring is classic and beautiful, but I don't have any photos to share just yet. This is the happiest moment of both our lives. He's my best friend and my soulmate."

It would have been Sheen's fourth nuptials. The former Two and a Half Men star was married to Donna Peele from 1995 to 1996, actress Denise Richards from 2002 to 2006 and Brooke Mueller from 2008 to 2011.
