After only a few months, the romance between Hilary Duff and Matthew Koma is over. E! News confirms the split happened in early March and was triggered by both of their “busy schedules” — Koma is now single and on tour. They both also stopped following each other on Instagram, which may signal that the split wasn’t as amicable as they’re making it seem. The actress is now back in NY filming the 4th season of “Younger”, and was also caught hanging out with her ex beau Jason Walsh.
