Jenny was very open about the shocking breakup and admitted that she remained resistant to divorce until it became inevitable. Nine months after the split was announced, Peter moved on with actress Jaimie Alexander, his co-star in the comedy Loosies. The 90210 star has reportedly also moved on, but so far is not revealing with whom.
