Terry Jones has three children - Siri, Sally, 35, and Bill, 32
Monty Python star Terry Jones has spoken for the first time about becoming a father again at 67.
Jones's 26-year-old girlfriend Anna Soderstrom gave birth to daughter Siri earlier this month.
He told Radio Times: "I don't think people who have children are acting selfishly or unselfishly."
The star, who already has a grown-up son and daughter, said: "Having a child who'll be loved, to parents who love each other, is the important thing."
He added: "I've a reasonable chance of living another 20 years, and hope I do, so Siri will be in her 20s."
Jones left his wife of more than 30 years to set up home with his Swedish girlfriend, who he met at a book signing, but refuses to talk about their relationship publicly because "it doesn't worry me what anyone says, except when publicity hurts others".
Jones said he was "yet to discover how I like having another child"
The Python star also told the magazine how he had fully recovered from colon cancer but had been left with slightly frozen feet.
He says it was a side effect caused by chemotherapy and is the only lasting effect of the disease after doctors discovered a tumour.
He said: "It never worried me because I wasn't ill. They cut it out and it hasn't spread. To play safe, they gave me chemo and I have slightly frozen feet as a side effect."
Monty Python's Flying Circus celebrates its 40th anniversary next week, and the five remaining members of the team will receive a special Bafta on October 15 at a reunion event in New York.
