The couple, who has been dating more than a year, broke up because there is an imbalance in their relationship.
AnnaLynne McCord is back on the single saddle after splitting from "Prison Break" star Dominic Purcell. The couple met in early 2011 while filming "Officer Down" and called off the relationship after 15 months.
Reason of their split is not yet revealed but a source told Us Weekly that McCord wants to settle down because both of her sisters, Angel and Rachel, have got engaged. "Though AnnaLynne's not in a rush to get married, her sisters getting engaged must have made her evaluate her own relationship to some degree," the insider said.
Purcell allegedly was more into her than she was into him, leading McCord to realize the "imbalance in their romantic dynamic." However, it was McCord who fell hard for the actor, who is 17 years her senior, at the beginning of their relationship.
