90210 vamp and the Twilight hunk have called it quits—or, rather, McCord decided to kick Kellan's keister to the curb.

"She broke up with him," an insider spills. "He wasn't a good boyfriend."

How so? Well, the Lutzter apparently swapped spit with another female over New Year's Eve, and while the source says that McCord "forgave him," Lutz made a second boo-boo by stiffing AnnaLynne on her birthday
"He showed up at her house with flowers and took her to dinner, but that was it," says the source. "No gift."
