Tinglan Hong, Mystery Woman, is Hugh Grant's Baby Mama

Hugh Grant is a father for the first time, after former flame Tinglan Hong gave birth to a daughter on Sept. 26.

The Daily Mail has disputed U.S. media reports that the child was born in early October, citing an unknown source who provided details of the birth. Hong reportedly had a C-section at Portland Hospital in London, and registered there under the alias Sophie Hong.

Tabloid speculation that Grant's casual girlfriend was pregnant surfaced this past April. Citing News of the World, Heatworld.com reported that Tinglan -- or Ting -- had been spotted with a growing baby bump.

An unnamed source reportedly told News of the World that Grant and Hong were enjoying each other's company but were not expected to get too serious.

Hugh and Ting have grown increasingly close in recent months. They see each other most days and she's a big part of his life. But watch out, he's still a free spirit, the source reportedly said. Ting's a lovely girl, smart and very attractive. She and Hugh love spending time together. But as ever he's a very difficult man to nail down. And although they're increasingly close, Ting's aware that he still goes out with other girls. Yes, he sees Ting all the time, but it's normally on his terms - at his house or bars and restaurants nearby. Hugh has always been a bit of a commitment-phobe. He just loves doing his own thing.

A statement from Grant's rep suggests that the 51-year-old actor is indeed doing his own thing.

I can confirm that Hugh Grant is the delighted father of a baby girl, the rep told Reuters. He and the mother had a fleeting affair and while this was not planned, Hugh could not be happier or more supportive.

According to the Daily Mail, Grant was not present at the birth of his daughter but briefly visited with mother and child the day after she was born -- for a whole half hour -- before heading to a golf tournament.
