Are AnnaLynne McCord and Dominic Purcell amicable exes -- or is there already a reunion in the works?
The newly split duo was spotted brunching together in Santa Monica, Calif. Friday. After their meal, the pair exited the restaurant with their arms wrapped around each other's waists.

Despite their midday PDA, as multiple sources confirmed to Us Weekly this week, the 90210 actress, 25, and the Prison Break star, 42, did indeed end things recently after 15 months together.
One insider cited an "imbalance in their romantic dynamic" as the reason for their split.

Purcell seemed "more into AnnaLynne than she was into him," the source explained.
The source added that McCord found herself questioning their relationship after her two sisters, Angel and Rachel, both 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 source told Us.

Another insider revealed that McCord "fell for Dom hard" in the beginning, and the couple was set on making it work, despite their 17-year age difference.
McCord and Purcell first met while shooting Officer Down in early 2011; that film has yet to be released.
