I did a corporate gig early in my career, and they opened the buffet in the middle of my set and everybody left.

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.

See my greatest fear!

When I was 11, I went down a water slide and my bottoms didn’t go with me. Everyone saw my bare white butt.

Listening to a song that my brother-in-law – the brother of Jason, my first husband – wrote, about how hard it was to live without his brother.

All the big ones – climate change, safety for our children, money.

My mum looks after our kids all the time, but on the very few weeks she takes time off, doing it all is a big juggle. My mum is a combination of Mary Poppins and Angela Davis, so I’d clone her.

When my first husband died, because it felt like my life was over, and it was challenging to keep in life at the time.

I wouldn’t change anything. When I was 29, my first husband died, so I learned a new way of thinking about life, which is: there are many things that you can’t control.

My mum, for the way that she brought up her three children and managed to make her money work. She worked as a cleaner for all these families we went to church with. She would cycle there with my little sister on the back of her bike – we didn’t have a car. She had an amazing mind for planning and organising so that we got to do ballet, we went to Brownies.
