Peter Facinelli and Jaimie Alexander have ended their relationship, their reps confirmed to ABC News in a statement.
The couple announced their engagement almost a year ago.
“Due to conflicting family and work commitments on opposite coasts, and after much consideration, Peter and Jaimie have chosen to part ways amicably and remain good friends," the statement read.
Facinelli, 42, and Alexander, 31, first began dating more than three years ago after they appeared on "Nurse Jackie" together. Last March, the "Twilight" star proposed to Alexander atop the Empire State Building.
"But we're toying with the idea of doing something kind of stunt-oriented to just mix it up and doing something kind of wild and fun," she said. "I just don't have it in me, that, like, girly gene that's, like, 'I need to be in a white dress.' I could be in a pair of jeans and be just as well."
