Tyger Drew-Honey, one of the child stars of hit comedy Outnumbered, is filming a BBC series about the sex industry starring his porn star DAD.
The 17-year-old, who plays Jake Brockman, wants to become a documentary maker following the end of the family series.
So he's going to interview his dad – known to the porn industry as X-rated actor Ben Dover.
Eye of the Tyger aims to turn the teenager into the 'new Louis Theroux'.
And dad Ben (whose real name is Lindsay Honey) has signed up for the BBC3 documentary.
Lindsay, 57, said: "Tyger's doing one programme on young people and pornography so I was interviewed by my son which was a bit weird. It is about how youngsters perceive pornography.
"Obviously producers thought if any young person is going to do a documentary about the sex industry then it has to be Tyger because his parents were involved in it."
Lindsay admitted Tyger was not previously aware of his work. He added: "I know he gets ribbed about what I do but he is totally grounded."
Mum Linzi Drew is also a former porn star and ex-Penthouse editor. She and Lindsay are separated.
A BBC source said: "It will be odd for viewers to see the lovely son they watched grow up talking about the sex industry."
