British film star Hugh Grant, 51, has become a father for the first time, it was announced Tuesday, but the identity of the mother remains a mystery. “I can confirm that Hugh Grant is the delighted father of a baby girl,” his New York publicist Carrie Gordon told AFP. “He and the mother had a fleeting affair and while this was not planned, Hugh could not be happier or more supportive,” she said. “He and the mother have discussed everything and are on very friendly terms.” Last April, the star of ‘Notting Hill’ was seen in London with a Chinese starlet, Hong Tinglan, who according to some tabloids appeared to be pregnant. Grant was previously in long-term relationships with model and actress Elizabeth Hurley and socialite Jemima Khan.
