90210 star AnnaLynne McCord is officially back on the singles market.
The 25-year-old has split from her older man Dominic Purcell, 42, after a 15-month romance, according to Us Weekly.
The pair got together while filming Officer Down early last year and seemed to be going strong, but sources say that AnnaLynne pulled the plug on the relationship after seeing how happy and in love her sisters Angel and Rachel are after getting 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 appeared to be] more into AnnaLynne than she was into him," and the actress "recognized the imbalance in their romantic dynamic."
Another insider revealed that AnnaLynne initially "fell for Dom hard" and "they made it work" for a while despite their 17-year age difference.
AnnaLynne got together with Dominic after her split from Twilight hunk Kellan Lutz, whom she dated on-and-off for three years.
