Sheen, 49, announced his decision to break off his relationship with Rossi on Friday. "Scotty and I had a great year together as we traveled the world and crossed a lot of things off our bucket list," he told Us Weekly. "She's a terrific gal, but we've mutually decided to go our separate ways and to not spend the rest of our lives together."

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

It was rumored back in August that Sheen and Rossi were about to call off the wedding. Apparently, Rossi had enough of her boyfriend's playboy lifestyle and tried to get him to cut back on his partying. Instead of obliging, Sheen allegedly started to spend even more time partying out of town.

“Charlie has been going out and leaving Brett at home. She lights up his cell phone demanding to know when he is coming home," an insider told Radar Online. "Brett forced Charlie to wear the wedding band, which he is wearing as an engagement ring. Charlie continues to hang around with other women, which infuriates Brett. It’s disrespectful to their relationship, and Brett wants to make it clear that Charlie is off the market.”

Sheen and Rossi, who became engaged over Valentine's Day weekend, had planned on tying the knot on Nov. 21.

Sheen has previously been married to Donna Peele, Denise Richards and Brooke Mueller. He has daughters Sam, 10, and Lola, 9, with Richards and 5-year-old twin boys Bob and Max with Mueller.
