Which moment embarrassed you most?

Sending a text meant for my wife to Dara O'Briain by mistake, revealing myself to be a control freak.

I don’t embarrass easily: I’m kinda shameless.

At a fashion show after-party in New York in 2004, my friend dared me to push her into the pool. I did, and you’ve never heard laughter die so quickly.

Farting in front of Colin Firth.

I remember being a teenager and writing this romantic short story in the style of the Brontës on a computer and I didn’t realise that the person whose computer it was could just print it out. A group of boys had a couple of pages and they were all reading it.

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

A gazillion years ago I was in Gucci with Melanie Blatt, and I attempted to sit down on a chair that wasn’t there. I did a full-on stuntwoman backward roll, landed in a ball of the floor and laughed so hard I wet myself. Everybody in the shop moved to a different section.

I was once walking through Edinburgh with someone in the industry. I was quite drunk and I slowly wet myself.

I have a deep-rooted fear of being in trouble. I once tried to sneak into the back of a photography exhibition with my husband when one of our kids was in a pushchair. We’d arrived late and he suggested we go in through the gift shop and see the last room. As we poked our heads round the door, the security guard noticed us. I shouted, “That man’s trying to get in!”, then ran away.

Being torn to shreds by a very elderly woman for driving badly on the Isle of Man, maybe 15 years ago. She stopped in the middle of the road and really let me have it.

I worked with Stephen Fry recently and we had a real heart-to-heart. I asked: “What was it like being in prison for being gay?” And thank God someone came in and he didn’t hear me say it. I was mixing him up with when he played Oscar Wilde. I could picture him in his cell.

Being an actor is inherently embarrassing. You have to embrace it.

I was in Oliver! when I was 10 and I peed myself on stage in front of however many people the Palladium holds. It was the stuff of nightmares.

When I was losing my sight, I couldn’t see where I was going, and I went into an undertaker’s thinking it was a barber’s. I asked the undertaker whether he had many waiting.

Leaving the stage from a panic attack in my 20s. Hearing the audience angry.

Being misrepresented by a Sun journalist 12 years ago.

After the 2012 Olympics I hosted the parade. I had on a little skirt and when the prime minister came on everyone cheered. I thought: “Oh my God, they love David Cameron,” but they were cheering because my skirt had blown up, and I’d flashed my knickers at him.

At school, I got my head stuck in a balustrade on the stairs at lunchtime. I had pupils laughing at me, parents laughing at me, teachers laughing at me and eventually, at the end of the day, the fire brigade laughing at me.

On radio, I once said “anal” instead of “angel”.

On one of my first jobs, Cold Mountain, I got a wasp in my ear in front of Jude Law. He couldn’t see the wasp so just saw me freak out.
