One of our favorite on- and offscreen couples, Nina Dobrev and Ian Somerhalder, have called it quits. The Vampire Diaries stars dated for over three years, and despite their breakup, they'll still be working together on set when the fifth season begins filming. Nina and Ian aren't the first TV costars to strike up a romantic relationship — small-screen duos like Rachel Bilson and Adam Brody, Blake Lively and Penn Badgley, and Vanessa Hudgens and Zac Efron also hooked up during their downtime, and leading ladies like Jennifer Garner, Emily VanCamp, and Sophia Bush were lucky enough to find love on more than one set. Click through to see 30 couples that took their love off screen — and even worked together well past their demise.
