If fatherhood came late to Hugh Grant, he is making up for lost time.

The 53-year-old actor has gone from being childless to a father of three in the space of just 15 months. His third love-child was revealed yesterday – a son born to Swedish television producer Anna Eberstein.

She would have been pregnant at the same time as Grant’s other lover Tinglan Hong, who gave birth to his son Felix Chang three months afterwards. Miss Hong is also the mother of Grant’s first child.
