Elizabeth Hurley said that starring in intimate scenes during her son Damian's new film Strictly Confidential was 'comfortable', quipping that she had been filmed by him ever since she gave him his first camera.
The actress, 58, said that she was first filmed by her son when he was ten and had been 'filming her ever since'.
She told the One show: 'He wrote sketches and initially little baby films and gradually go up to making bigger films.
'I always said I'd be in his first film, and because he filmed me so much, and because I often force him to take photo ops of me all the time, it just seemed like nothing.
'It was a very low budget film. It was just like do it and knock it out and get going.'

Damian added: 'This has been such a whirlwind. It was so amazing. It was really amazing we had tons of family and friends.'
Talking about shooting the film's steamy scenes, which includes Lesbian sex, Liz said: 'Everyone knows it's not actually sexy to shoot any kind of intimate scene. It's just technical. And we'd rehearsed it. Damian made it so comfortable. It was nothing.'
Damian has defended his decision to direct his mother in the film's racier moments, and revealed they didn't even have an intimacy co-ordinator on set.
'What was really nice was that in the audience for, for my all friends and family, was that every single person has known him since the day he was born', said Liz.
'So to see him do this..it felt really nice.'
She added: 'I think it was the most nervous I've ever seen you [Damian].'
The production wasn't without its hiccups though, with the mother and son revealing that they had trouble shipping in the costumes to the film's shooting location in St Kitts and Nevis.

The mother and son also revealed that several of the film's costumes got stuck at customs in St Kitt's and Nevis, leaving Damian's 'male godfather' to smuggle them in, including 80 bikinis
Damian revealed that his 'male godfather' was forced to smuggle in 80 bikinis after they were stopped by customs.
Damian said: 'This was about a week before we were meant to be shooting. I think about 80% of our costumes got denied entry at the border and were shipped back to the US.
'There aren't really any costume shops. There's no infrastructure there for a movie.
'So I persuaded my male godfather to fly about hundred costumes in, smuggled them in the suitcase and everybody wanted their bikinis.
'So my godfather was standing there and was like 'of course these 80 bikinis are mine. What are you talking about? So they made it.'
Asked whether that was Grant, he replied: 'He's not the bikini smuggler, but he is a godfather.'
