13 celebrities that you didn't know dated

The world of celebrity relationships is one that remains relatively shrouded from us. Read all the tabloids you want and you'll only ever uncover is tiny tidbits of information which only give way to speculation and rumour, not fact. We can deny it, but we all have voyeuristic tendencies - the majority of which tend to revolve around whether our favourite on-screen coupling is translating into a romantic liaison off-screen. And it's hard not to care - we see these faces, day in and day out on shows such as Game of Thrones, Stranger Things and whatever new original Netflix has released. I mean, who wasn't secretly elated that Jon Snow and Ygritte found a way to be together outside of Westeros? And before you start worrying about me, no, I don't really care, but considering that we live in a world full of stress (commuting, finances, grocery shopping, you name it), it's quite nice to de-compress with a bit of good ol' fashioned gossip at the end of the day. So let's dive into something particularly salacious today, shall we? Here are 13 celebrities who managed the impossible and actually kept their relationship out of the press - some even managed it for years!

1. Matthew Broderick dated his Ferris Bueller's Day Off co-star Jennifer Grey without the press knowing until they were both involved in a horrifying car-crash in 1987

2. Big Bang Theory co-stars, Kaley Cuoco and Johnny Galecki dated in secret for two years 

3. Lena Headey and Jerome Flynn aka Cersei Lannister and Bronn were together for a year back in 2002, but things ended so badly that they are "no longer on speaking terms" and have to be kept apart on the set of Game of Thrones 

4. Alexis Bledel & Milo Ventimiglia kept their relationship a secret for three years before breaking up in 2006. They met on the set of Gilmore Girls, naturally
