Minnie Driver has identified her son Henry's father after years of keeping him a secret.
The 42-year-old actress told The Observer that her three-year-old son's father was a writer on her former television show The Riches.
It had previously been reported Henry's father had ended their relationship when she fell pregnant, but Minnie revealed he is now becoming more involved in their son's life.
Minnie said: "I don't need to protect him anymore. He can fend for himself. He's a grown-up.
"We weren't together and he wasn't directly in the business so I chose to protect him and not have a rain of publicity. He's not famous. There's no big story."
She added: "Is he a good dad? Sort of. He's figuring it out... I mean, he hasn't been that involved, his choice. But he is now."
The Conviction star - who plays a teacher in Marc Evans' new musical Hunky Dory - has previously admitted she would like more children, but she doesn't think she could cope raising two children as a single mother.
Minnie said last year: "Henry's dad and I probably wouldn't have any more together, but I would love to have more.
"But I couldn't do another one without a partner; I couldn't do two as a single mum, I really couldn't. It would be too much."
