Alexis Bledel and Milo Ventimiglia
They may have played your favourite on-again, off-again couple, Rory and Jess on Gilmore Girls, but they also dated in real life for a whopping three and a half years.
Emily VanCamp and Josh Bowman
They were literally the worst couple ever on Revenge, but in real life they are living a fairytale. The couple became engaged earlier this year, after dating since 2011.
Kit Harington and Rose Leslie
Game Of Thrones stars Kit and Rose found love while they played the rough-yet-lovable duo of Jon Snow and Ygritte. They're so loved up, they've even been at the centre of a few engagement rumours recently.
Jennifer Garner and Scott Foley
Jen had a small role on Felicity as Noel's long-distance (then ex) girlfriend Hanna. After playing love-interests on the show, Jen and Scott married in 2000 before divorcing in 2003.
Kaley Cuoco and Johnny Galecki
They might be married and totally loved up on The Big Bang Theory, but in real life their romance was not meant to be. The duo dated in secret for two years, only revealing their romance once it was over.
Despite being exes, these two are thick as thieves and remain incredibly close on and off the set.
Penn Badgley and Blake Lively
Ahhh, another couple who had to get fake-married long after their real-life love was over.
Serena and Dan may have found their way back together after years of drama on Gossip Girl, but IRL the duo found love with others. Blake, with the amazing Ryan Reynolds, and Dan with the ever-cool Domino Kirke.
Nina Dobrev and Ian Somerhaulder
The Vampire Diaries co-stars didn't work out on the show, or in real life. They remain friends, however, and have both found love outside the show. Ian married Nikki Reed, and Nina is currently dating actor Glen Powell.
Ginnifer Goodwin and Josh Dallas
Once Upon A Time's very own Snow White and Prince Charming actually dated in real life, before tying the knot AND welcoming their first child in 2014. Fairtytales are real, you guys.
Rachel Bilson and Adam Brody
Ah, Seth and Summer. The iconic TV couple you idolized in your youth. Unfortunately these two never made it to "I do" like their characters, but they did find romance.
Rachel is married to Hayden Christensen, while Adam is married to "Blair Waldorf" AKA Leighton Meester. So, Blair and Seth is kind of just as exciting, right?
