The former MTv girl broke up with Turner in 2011 after four years together, and the romance had come hot on the heels of her three-and-a-half year relationship with photographer David Titlow.
Chung was left distraught by the split and has only allowed herself several casual flings since the break-up, because single life made her realise she did not even know how to change Tv channels properly.
She tells Britain's The Guardian, "I'm not heartbroken any more, but I definitely was... It was various people. There was one big thing, and then there were various ill-advised flings I had to get over him, so yeah... But is this gross to talk about? I feel he wouldn't talk about it. I don't know how relevant it is now, whereas if you asked me at the time, 'How you doing?' No one even asked... But I don't know whether to be open and vulnerable about it and say, 'I had a s**t time', or to be quiet...
"But I don't want to imply he broke my heart. I was grieving for the loss of something... I'm grateful for the experience of that s**t time, and for being on my own. I'd never really been on my own before - I'd always gone from one relationship to the next - so I had to learn all this stupid stuff. Like, how do I work my f**king Tv? And now there isn't a dude to tell me how to put up the blinds. But it's good to learn how to work your way round a drill."
However, Chung reveals she still remains close to Turner, adding, "Oh yeah, he's my best friend."
