Hugh Grant has become a dad after the birth of his first child, a daughter, his rep confirms to PEOPLE.

“I can confirm that Hugh Grant is the delighted father of a baby girl,” the rep says in a statement.

“He and the mother had a fleeting affair and while this was not planned, Hugh could not be happier or more supportive. He and the mother have discussed everything and are on very friendly terms.”

The longtime bachelor, 51, who famously dated Elizabeth Hurley for 13 years, then Jemima Khan for three, has not revealed who the mother is. He was last romantically linked to Chinese actress Tinglan Hong.

The actor, who has never married, said in 2009 that he “hadn’t given up hope” of becoming a parent, adding that he “finds I’m not as bad with children as I used to be.”
