At the TV Baftas last year I was wearing these heels that had stiff bows on the front. One heel locked into the other bow and I went arse over tit.

Helen Mirren was in the elevator with me at the National Theatre. She pressed the button but it didn’t move. I said, “Fancy seeing you here and being stuck in an elevator.” And she said, “Was that meant to be funny?” I apologised, and she laughed. Even talking about it now, it feels so awkward and embarrassing.

One time I got so drunk in the Soho theatre in London that I fell asleep in the disabled toilet for two hours. People still call the toilet Rosie’s Bedroom.

Gloria Hunniford’s wedding at Hever Castle 20-odd years ago. We had a lovely buffet and a few drinks and then I had to get a cab back to the train station. I said to the driver: “I’m ever so sorry, but I’m not going to be able to hang on till I get to the train. Could you possibly take me down this alleyway?” He said: “Yes, of course.” As I prepared myself to go “to the ladies”, this police car came along and the policeman said: “Hi-de-Hi!”

Losing out on a role, any role. I get so invested. I can take rejection, but only when useful feedback is given.

Narcissism. And people coughing on me in public.

A horse-riding accident when I was about 15.

“You were amazing in Game of Thrones.” I say it’s the worst thing – it’s also the best!

Endless acting jobs.

A few of my exes.
