Australian model Sophie Monk has confirmed that she and Benji Madden have officially split up. Following a month of speculation, Monk’s agent Yoon Kim has revealed that the couple has called off their engagement yesterday.

She said, “Sophie and Benji have officially split. The decision was mutual and they remain amicable.”

The couple’s romance began 18 months ago after they met on the set of a Good Charlotte video. Benji proposed to Sophie last year. The rumors of their split started when she failed to wear her engagement ring at a string of recent high-profile events.
