UsMagazine.com reports that "they fought a lot. It was always on and off. He's a creative mind so not the easiest person to be in a relationship with."
A rep for the "True Blood" actress hadn't responded to MTV News' request for comment by press time.
The two have reportedly always been very on-and-off. After initially dating in 2006, they split two years later before reconciling and getting engaged earlier this year. During their time apart, Wood was reportedly dating "Nikita" star Shane West. This time, it seems Manson is handling his broken heart by hitting the town.
Manson, who was once married to burlesque star Dita Von Teese, and guitarist Twiggy Ramirez were seen getting their party on in Los Angeles on Saturday night. They had dinner at hotspot STK before getting their dance on at Boudoir along with Playmate of the Year Colleen Shannon. E! News reports that Manson also had an unidentified brunette with him and was introducing her to people as his new girlfriend.
"They just broke off their engagement, and he needed a night out with friends," one source told People.com.
Last year, Wood spoke to MTV News about Manson, saying, "We have the same sense of humor." And she admitted that no one was too surprised by the pairing. "They would be more shocked about [my 'Whatever Works' co-star] Larry David," she joked. "Nobody asked me why — they asked me how."
