When were you most embarrassed?

Modelling tuxedos at the Oklahoma State Fair in 1971.

Appearing on a Paris catwalk in a beard.

Playing a pregnant woman, and not being able to find the padding - I shoved a cardie under my dress, and spent the whole play walking around with a sleeve dragging along the floor.

My brother was singing Yellow Submarine on stage with his class. I was singing along with them, showing off cos I knew all the words. The song ended suddenly and I was the only one in the whole hall who sang, 'We ...'

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

See my greatest fear!

Walking with Eric Clapton’s tour manager Mick to meet Eric backstage, and when I met Eric I said, “Hi Mick.” I wanted to die.

When my trousers nearly fell down at Buckingham Palace. I was there to collect my OBE, and the suspenders for the beautiful Alexander McQueen suit I’d had made for the occasion went missing. Naomi Campbell was with me and we had a good laugh about it.

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.

I was in Kensington Gardens and this couple stopped me and said: “Hey, could we get a picture? I said: “Sure.” I put my arms around their shoulders, and they looked at me and said: “No, can you take a picture of us?”

When you jump out of addiction and look back, things like drink-driving and sitting in crack houses are not good.

When I was starting out, in the early 90s, I had to fake an orgasm in a room full of male ad execs at an audition for a chocolate bar ad. It was grim.

Missing a cue on stage. I had to come on and move a piece of furniture with another actor and I completely forgot. I looked at the monitor and said, “Why is he standing on his own?” And somebody said, “Aren’t you meant to help him?”

I was in the musical Elvis, and after a costume change I went below stage to be raised up on a platform. As I was raised up, I blanked and couldn’t remember the first line of the song King Creole. I mumbled the first few lines and hoped nobody would notice.

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

On stage in Tasmania, I tripped over a floor monitor and landed on my back like a turtle, kicking my legs in the air trying to get back on my feet in front of about 5,000 people. But when I got on my feet, the whole crowd roared in triumph.

Going to pieces while meeting John Squire, the lead guitarist of the Stone Roses, backstage after a gig. I completely lost the ability to speak. I told him I had the same guitars as he’d just used on stage, and when he asked me which ones, the words completely went out of my head and there was a huge pause, and then his wife tapped his shoulder and he wandered off.

Being on the cover of a magazine at 18 with the slogan: “Did she ruin The Godfather?”

I started stammering badly the first time I was on live radio, on Woman’s Hour on Radio 4. When I think about it now it brings me out in a cold sweat.

I was doing a photoshoot right after an awards show and I was talking about someone whose makeup I really didn’t like. I said: “She’s gorgeous, I don’t understand how a makeup artist could encourage that?” And the makeup artist on the photoshoot said: “I did her makeup.”
