If you follow Hilary Duff on Instagram, you may have noticed that there's a special man in her life. Of course there's her son Luca, but we're also talking about her boyfriend, writer/producer Matthew Koma. If he looks familiar, it's because the two have dated before. In fact, this is the third time they've gotten back together, actually. Hilary Duff recently appeared on the show The Talk to dish to Sharon Osbourne and the gang about the real deal behind her rekindled romance.
