Once the DNA tests confirmed Bing was the father, his publicist Sue Stapley insisted the producer was 'pleased'.
'Steve wanted the tests done,' she said. 'He wanted this issue dealt with as quickly as possible and is pleased with the result.
'At no time has he ever denied that he will be a part of Damian's life if the tests proved he was the father.
'He always stated that he would be a generous father and is now looking forward to being a part of Damian's life.'
In an interview this week, Miss Hurley said: 'Motherhood has been a huge learning curve, but it has been a nice thing as it happens.
'I do everything I possibly can to make Damian happy. I don't think being a mother has changed me. It has added to me. I just feel much, much happier.'
Miss Hurley, who dated Hugh Grant for 13 years, reveals she had to exercise rigorously to lose the 53lb she gained during her pregnancy.
'Losing the weight was mostly iron will,' she said.
'I made it my mission to get back into shape. I exercised more than I ever have in my whole life.
'I have just started coming back to work. Obviously, I had to take some time off because I was the size of a tank.'
Miss Hurley and Damian live in a £2million house in Chelsea. Hugh Grant, one of her son's godfathers, lives a few doors away.
