AnnaLynne McCord & Kellan Lutz SPLIT: Breakup For Actress & Actor

AnnaLynne McCord and Kellan Lutz have broken up, Life & Style reports.

GossipCop has confirmed that the couple split about a month ago and AnnaLynne spent Halloween hand in hand with with model Aaron O'Connell.

Life & Style's press release follows:

Life & Style's Scene Queens can exclusively report that after almost two years of dating, Twilight hottie Kellan Lutz and 90210 star AnnaLynne McCord have officially called it quits, a source confirms.

Rumors that the couple finally ended things began swirling after AnnaLynne and Kellan were spotted partying separately over Halloween weekend. "AnnaLynne was getting cozy with model/actor Aaron O'Connell while at Veuve Clicquot's Yelloween at LAVO in Las Vegas," an eyewitness tells the Scene Queens. "They were holding hands and flirting all night. The two are clearly a couple. They looked cute together." Meanwhile, Kellan was partying at the Borgata in Atlantic City on Oct. 30. "Kellan relaxed at the spa," an eyewitness tells the Scene Queens. "He definitely seemed like a bachelor."

The twosome have had an on-again, off-again relationship since early 2009, when they were first spotted kissing on Valentine's Day in New York. Though reports surfaced that they called it quits months later, the couple were photographed smooching in Los Angeles on Oct. 26, 2009. Despite a year of insisting the two were just friends, AnnaLynne finally admitted to the relationship in September.

"They just weren't compatible, so they are taking a break," the source tells the Scene Queens. "AnnaLynne seemed really happy over the weekend. I'm not sure Kellan was the right person for her."

A rep for AnnaLynne had no comment.
