The very first day that I was filming Top Gear, for which I was so unqualified because I’d only ever driven a Fiat Uno. I got into a DB7 Vantage Volante outside the Aston Martin factory, put my foot on the accelerator and bunny-hopped across the gravel because I’d forgotten to take the handbrake off.

Forty-eight hours after giving birth, I sent a picture that someone had sent me of their baby to a WhatsApp group, thinking it was my son (they kind of looked similar). Mortifying.

Falling flat on my face in Billy Elliot on Boxing Day when I was 14. I fell smack bang at the end of my number. I was mortified.

At the Mighty Hoopla festival, Kimberley and Nicola from Girls Aloud joined me on stage for a Girls Aloud song. I completely forgot the words.

My short film, Scrubber, in 2011. At that time in my life it seemed easier to pay for it myself than to apply for funds.

Those abduction situations where you’re packed in a bunker for 30 years.

I’ve done some acting jobs where everybody’s gone out of their way to make sure that you feel annoying and easily replaceable.

Anybody who works in frontline mental health services for the NHS.
