Joanne King: (About her plans of future) I'm not prepared to just settle for Mr Ok. He has to be Mr. Right. I'm happy being single for now but I'd love to settle down one day and have a big Irish family - Daily Mirror, March 24, 2007.
Joanne King: (About her eating habits) Personally, I like good food and lots of it. I don't believe in denying yourself treats. I hate the gym but yoga is brilliant. It's part of me - Daily Mirror, March 24, 2007.
Joanne King: (About her lifestyle) I don't live a glamorous lifestyle. I'm more at home in my trackies than I am getting dressed up. When I'm off work I don't bother wearing any make-up - Daily Mirror, March 24, 2007.
Joanne King: (About her taste in men) I prefer my men to be a bit scruffy, I'm not into the clean-cut look. But talent is very sexy as well - Daily Mirror, March 24, 2007.
Joanne King: (About her hometown) I don't get home often enough. I love it back in Dublin. We have the most beautiful theatres and wonderful people. I love going back - Daily Mirror, March 24, 2007.
Joanne King: (About shopping) I love a bargain. When something's half-price I get all excited about it. I like vintage clothes and get a lot from secondhand shops. Moneywise, things are more stable for me now but I'm not at the stage where I can go out and buy a Hollywood mansion - Daily Mirror, March 24, 2007.
Joanne King: (About her struggle before becoming an actress) Life was hard. I moved to London determined to become a successful actress but it's not that simple and I had so many jobs just to get by. I was sharing a flat with a friend and we had to get out in a hurry because we couldn't afford the rent. London has so much to offer young people but I couldn't be part of that because I had no money. Every penny counted. I really didn't think it was worth the heartache anymore. All I wanted was to act but it's tough and I've done some ridiculous jobs to see me through – Daily Mirror, March 24, 2007.
