American actor Jordan Firstman has shared he has become an uncle – while also revealing he is the baby’s biological dad.

In a new interview with W. Magazine, the Club Kid actor and director, 35, revealed that he was asked to be his sister’s sperm donor so that she could have a baby with her wife.

He went on to say that the baby was born on the last day of production for Club Kid.

He said: ‘It was coincidental,’ Jordan said of the similarities between his real-life story and the story of his film, which follows a club promoter who learns he fathered a 10-year-old boy.

‘I had written the first draft, and then my sister asked for my sperm [for her wife].’

Jordan said it was a ‘total no-brainer’.

‘Total no-brainer. The baby was born on my last day of production. Very emotional, very hard to process. But — I’m an uncle, let’s be clear. I’m not doing any fatherly duties. I smile on FaceTime and send her gifts. My sister and her wife are so happy,’ he added.
